Problems noted by Stepan Kasal. Also, throughout this document, be more careful about white space. "blank", "white space", and "space" all have different meanings and we should be careful to say what we mean. 2005-05-05 Paul Eggert Fix C++ related problems reported by Werner Lemberg. * doc/autoconf.texi (C++ Compiler): Mention .cpp extension. * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc. * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to avoid problems with C++ and throw. * tests/compile.at: .cpp, not .cc. * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change. 2005-05-05 Ralf Wildenhues * doc/autoconf.texi (Generic Functions): Typos. 2005-05-02 Gary V.

(m4_strip): Update the explanation. 2005-04-19 Paul Eggert * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE): Remove core.conftest.* too; it's generated by Tru64 5.1. Problem reported by Jennis Pruett. * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL): Don't bother to remove core files; AC_RUN_IFELSE should do that for you. 2005-04-19 Stepan Kasal * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too. 2005-04-19 Alexandre Duret-Lutz * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

Problem reported by Ralf Wildenhues. 2005-03-22 Ralf Wildenhues * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Merge `-z option' as well for the benefit of Solaris link flags. Pass whole-archive (-zallextract, -zdefaultextract) options in the hope of unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported against Libtool by Yury Puhalsky . 2005-03-22 Paul Eggert * NEWS: The configure command now warns you if you attempt to use a directory whose name contains a special character like space, newline, or "\". * doc/autoconf.texi (Installation Directory Variables): Allow "," in file names. Do not use \@; it's not a portable regexp. * bin/Makefile.am (edit): Likewise. * lib/Makefile.am (edit): Likewise. * tests/Makefile.am (edit): Likewise. * tests/semantics.at: Likewise. * tests/torture.at: Likewise. * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise. * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise. * doc/autoconf.texi (File System Conventions): Warn about unportable file names. * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.

".)" needs a following @: if not at the end of a sentence, and similarly for "!)". "etc." should be preceded by a comma. "n-th" -> "@var{n}th". pdksh is still buggy, so update its date. 2005-03-22 Bruno Haible * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's argument is often called 'build-aux'. 2005-03-07 Stepan Kasal * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the macro AC_TRY_LINK is obsolete.

(AC_PROG_CXX): Behave according to the documentation: don't search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC; make the variable CCC precious; use `cl.exe', not `cl'. 2005-02-23 Paul Eggert Alexandre Duret-Lutz * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from /dev/null, as "configure" shouldn't read stdin, and this insulates us from problems (e.g., when testing for "cl"). Also, do this redirection before invoking "hostname" or "uname", and keep the original input stream available via... (AS_ORIGINAL_STDIN_FD): ... this new macro. (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't bother with " * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to newline if neither \c nor -n work, as that would output two newlines. Prefer -n to \c. Reported by Stepan Kasal. 2005-02-12 Stepan Kasal * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define. This causes that any required macros inside will get before the if. * doc/autoconf.texi (autom4te.cache): A typo. 2005-02-12 Paul Eggert Undo previous change, except keep the change to lib/autoconf/programs.m4 that replaced grep with shell pattern-matching. This is because net-snmp configure reads stdin. Reported by Noah Misch. 2005-02-11 Paul Eggert * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from /dev/null, as "configure" shouldn't read stdin, and this insulates us from problems (e.g., when testing for "cl"). Suggested by Alexandre Duret-Lutz. Also, do this redirection before invoking "hostname" or "uname". (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Undo previous change, as it's no longer needed. * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with " * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to avoid thinking that Allegro Common Lisp's "cl" command is a C++ compiler. 2005-02-09 Paul Eggert * doc/autoconf.texi (Limitations of Usual Tools): Document that grep -q isn't portable. Improve grep -s explanation. Problem reported by Dan Manthey. 2005-02-08 Paul Eggert * doc/autoconf.texi (Special Shell Variables): Clarify PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan. 2005-02-07 Paul Eggert * doc/autoconf.texi: Use @acronym for DJGPP. Fix some @code's that should have been @env's, and vice versa. Sort environment variable names. Mention that shells no longer inherit IFS. Don't recommend PATH_SEPARATOR=';' so strongly. Mention that $RANDOM might expand to the empty string. "symlink" and "soft link" -> "symbolic link". Improve mktemp description (reported by Bruno Haible). 2005-02-05 Paul Eggert * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg. * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING): Likewise. * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS): Likewise. 2005-02-04 Paul Eggert * NEWS: Mention AT_COPYRIGHT. * tests/local.at (AT_CMP): Use diff directly on input files rather than copying them. * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in /usr/xpg4/bin since that sed dumps core (at least on Solaris 8). 2005-02-04 Noah Misch and Paul Eggert * tests/autotest.at (Empty test suite): New test. * tests/torture.at (Substitute and define special characters) (Substitute a 2000-byte string, Define to a 2000-byte string) (Substitute a newline, Define a newline): New tests. 2005-02-04 Noah Misch * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04. * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.

Add test to check whether positional parameters are restored after function return. 2005-02-02 Paul Eggert * doc/autoconf.texi (Special Shell Variables): Mention _, BIN_SH, DUALCASE. Say that variables other than "status" are safe if they contain a lower-case letter. The DUALCASE problem was reported by Ralf Wildenhues. * bin/autoconf.as: Don't exit with status 0 after write failure with --help or --version. * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise. * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise. 2005-02-02 Ralf Wildenhues * doc/autoconf.texi (Limitations of Usual Tools): Unicos 9 sed limitations. * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77 to get the option-enhanced interface on older Crays. Try ftn for Fortran 95 (newer Crays). 2005-02-01 Paul Eggert * man/Makefile.am (.x.1): Go back to the simple solution, but take care to echo the commands, so the user knows what's going on. Modified from a suggestion by Stepan Kasal. * doc/autoconf.texi (autoreconf Invocation): Mention autopoint, with a cross reference.

AC_REQUIRE). Update the long comment explaining it. m4_require no longer writes an ``is required by'' line to the execution stack. It contains only one bit of non-redundant information: that the macro was required, not called. And even this bit is useless in most situations: have you ever met a macro which both calls and requires the same macro? * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion... (_m4_defun_pro_outer): ... only via this macro, for the outermost macro. (_m4_defun_epi, _m4_defun_epi_outer): Complementarily. (m4_expansion_stack_pop): Remove the misplaced comment.

Suggested by Stepan Kasal. 2005-01-20 Paul Eggert * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement. Warn about newline stripping in `` and $(). Update Solaris version to 9. (Limitations of Builtins): Use expr "X...", not expr "x...", as X insulates us from future changes to Posix.

Update datadir, infodir, and mandir. Adjust argument parsing code. (_AC_INIT_HELP): Update help text. * doc/autoconf.texi (Installation Directory Variables): Document new variables. 2005-01-04 Noah Misch * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does not seem to work, assume it does set $(MAKE). * doc/autoconf.texi (AC_PROG_MAKE_SET): Update. 2005-01-03 Stepan Kasal * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting. 2005-01-03 Stepan Kasal A cleanup of the diversion support in m4sugar. * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description. (_m4_divert_n_stack): New macro; the expansion is m4_divert_stack, if m4_divert_stack is defined, and void otherwise. (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it. (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word stored in _m4_divert_diversion or _m4_divert_dump.

Suggested by Stepan Kasal. * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES. Add *.tmp. (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate, ifnames): Factor common code. And they said it couldn't be done! 2004-12-09 Paul Eggert * bin/.cvsignore: Add autoconf.in. * tests/.cvsignore: Add wrapper.in. * lib/autotest/general.m4: Escape '$' in case pattern. 2004-12-09 Noah Misch * man/Makefile.am (autoconf.1): Regenerate when `autoconf.as' changes. * lib/autotest/general.m4 [--trace] (AT_INIT): Do not `set -v'. * tests/autotest.at: New file. * tests/suite.at: Include it. * tests/Makefile.am: Distribute it. * lib/autotest/general.m4 [--trace] (_AT_CHECK): Do not enable shell tracing on a command that could contain multiple lines. * doc/autoconf.text: Document that fact and its implications. * lib/m4sugar/m4sh.m4 (AS_ESCAPE_FOR_EXPAND): New macro. * tests/autotest.at (Multiline backquote command substitution, Multiline parameter expansion, Literal multiline command, Multiline parenthetical command substitution): Remove XFAIL. 2004-12-09 Paul Eggert * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB and suggest AC_SEARCH_LIBS.

We don't want to disable extensions. 2004-11-29 Paul Eggert * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}. (Using Autotest, testsuite Scripts, Writing testsuite.at): Reword slightly to avoid some English-language problems noted by Ralf Wildenhues in: http://lists.gnu.org/archive/html/autoconf-patches/2004-11/msg00027.html 2004-11-29 Stepan Kasal * NEWS: Add ^L above each release. 2004-11-28 Paul Eggert Fix documentation problems reported by Russ Boylan in , along with some nearby cruft. * doc/autoconf.texi (Libtool): Libtool can be used without Automake (not without Autoconf).

Problem reported by Noah Misch in . More fixes to support spaces in the name of the build directory. This isn't a complete fix but it's an improvement. * bin/autoconf.as (autom4te_options): New var. Use it instead of appending to AUTOM4TE, so that we can allow spaces in the build directory's absolute name. * bin/autoheader.in ($autoconf): Allow spaces in file names. * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK, AT_CHECK_NOESCAPE): Likewise. * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir, main program): Likewise. 2004-08-18 Paul Eggert * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

From a suggestion by Kevin Ryde. * lib/Autom4te/General.pm (END): Return correct exit status even if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503. 2004-08-09 Paul Eggert * tests/torture.at (Deep Package): Use configure.in, not configure.ac, for compatibility with Automake 1.4. Reported by J C Fitzgerald in . 2004-08-04 Alexandre Duret-Lutz * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro. (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess. * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh. * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE. * lib/autom4te.in (Automake-preselections): Preselect AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it. 2004-08-02 Alexandre Duret-Lutz * lib/autom4te.in (Automake-preselections): Preselect AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will trace them. 2004-07-29 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for Tru64. * doc/autoconf.texi (Shellology): Mention BIN_SH. Document problem with "`""`" in pdksh POSIX mode. 2004-07-27 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix" with pdksh, too. Problem reported by Patrick Welche via Gary V. Vaughan. * doc/autoconf.texi (Shellology): Note that set -o posix is useful for pkdsh, too. 2004-06-24 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require _AS_UNSET_PREPARE, so that we can use $as_unset directly. Don't fail if ENV or BASH_ENV is readonly. (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL, etc. are read only. Problem reported by Ludovic Courtes. 2004-06-23 Noah Misch * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is zsh, disable GLOB_SUBST to avoid backslash handling problems. (trivial change) 2004-06-04 Paul Eggert * doc/autoconf.texi (File System Conventions): Warn about names like "aux". Problem reported by Eric Blake. * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division by zero instead of array size, so that we can use any arithmetic constant expression (instead of requiring an integer constant expression). This allows us to test expressions like DBL_MAX < LDBL_MAX, which didn't conform to the C standard using the old method. (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON, now that we can do floating-point tests at compile time. 2004-06-02 Paul Eggert * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX and LDBL_EPSILON, as the resulting expression isn't an integer constant expression and violates the C standard. Problem reported by Nelson H. F. Beebe. Also, check for "L" suffix, and check that long double doesn't have worse range or precision than double, that mixed-mode arithmetic doesn't generate a diagnostic, that double constants fit in long double. 2004-06-03 Kevin Ryde * doc/autoconf.texi (Function Portability): Add notes on free(NULL), malloc(0) and realloc(NULL,size). * doc/autoconf.texi (Shell Substitutions): Spelling error reported by Bob Proulx. 2004-05-31 Paul Eggert * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported by Jim Meyering. 2004-05-26 Paul Eggert * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND can be rewritten using if-then-else. Suggested by Bruno Haible. 2004-05-25 Paul Eggert * doc/autoconf.texi (testsuite Scripts): Fix typo. Problem reported by Stepan Kasal. 2004-05-24 Paul Eggert * tests/Makefile.am (autoconfdir): Fix to match comment (trivial change). Patch reported by Ralf Wildenhues in . * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a function F exists if the compiler and linker let you compile an expression like (F != 0). Recent versions of GCC optimize away the reference to F in that case, since every function address must be nonzero, so the link succeeds even if F does not exist. Problem reported by Manu in . * doc/autoconf.texi (Systemology): Standardize on the spelling of "Unix". Many uses changed. (Limitations of Builtins): Explain better why the ! command isn't portable. 2004-05-22 Alexandre Duret-Lutz * lib/autom4te.in (Automake-preselections): Preselect LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS. 2004-05-19 Kevin Ryde * doc/autoconf.texi (Function Portability): Add strerror_r, cross referencing AC_FUNC_STRERROR_R. * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID, note pessimistic assumption when cross compiling. 2004-05-16 Paul Eggert * doc/autoconf.texi (Limitations of Make): Note that BSD make (until 2004) invoked subcommands with sh -e, contra POSIX. Reported by Kevin Ryde. 2004-05-10 Eric Sunshine * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e. " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as `test -f " /usr/bin/grep"', which _always_ failed. (AC_PROG_SED): Ditto bogus PATH fix. * autoconf.texi (AC_PROG_GREP): Properly document that this macro requires that grep correctly supports _multiple_ `-e' options, rather than stating only that grep should accept `-e'. 2004-05-03 Paul Eggert Port to C99, which requires that 'exit' be declared. * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT to ensure that stdlib.h is included. * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP, AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK, _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise. * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise. * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise. * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include when using 'exit' in a test; C99 requires that 'exit' be declared. 2004-05-02 Paul Eggert * doc/autoconf.texi (Particular Programs): AC_PROG_GREP now prefers 'grep' implementations that accept -e. (Limitations of Usual Tools): Describe problems of traditional egrep and fgrep with long input lines, and of traditional grep with -e. * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too. (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell. All callers changed. Append /usr/xpg4/bin to the PATH, for Solaris. (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother the user with complaints about multiple -e options. * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep. Define it with AC_PROG_GREP. * configure.ac (AC_PROG_GREP): Add. * lib/freeze.mk (GREP): New macro. 2004-05-02 Eric Sunshine * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as a possible candidate only after all others fail, rather than consulting it first. This improves backward compatibility by better reflecting the way shell selection occurred in previous versions of Autoconf, and should help to avoid triggering latent problems in other packages, such as the one in Automake where zsh is not handled robustly: http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html Although it is not Autoconf's responsibility to work around problems in Automake, it nevertheless makes sense to avoid introducing unnecessary incompatibilites. 2004-04-22 Albert Chin-A-Young , Gary V. Vaughan * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess how deeply nested we are when a suitable tool is found, set the ac_path_TOOL_found flag. (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply nested we are in this macro. Break out of all 3 nested loops if ac_path_TOOL_found is set. 2004-04-21 Gary V. Vaughan * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out of the _AS_PATH_WALK loop too if GNU flavor is found. 2004-04-21 Alexandre Duret-Lutz * doc/autoconf.texi (Limitations of Make): Update documentation for `$<'. New entry `Long lines', based on a report from Simon Josefsson. Augment the documentation for SHELL = @SHELL@ with a paragraph about DJGPP, based on a mail from Richard Dawe. 2004-04-20 Paul Eggert * tests/c.at (C keywords): Don't assume that GCC supports "restrict" and "inline", as sufficiently-old GCC versions do not (also, GCC configured to be in pedantic C89 mode does not). Problem reported by Sumit Pandya in: http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't consider -g to work if it generates warnings when plain compiles don't. Problem reported by Braden McDaniel in: http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html * doc/autoconf.texi (Slashes): New section, to document a problem reported by Jim Meyering in: http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential linker output files before linking, to work around IRIX 6 linker bug. Problem reported by Rainer Orth in: http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html 2004-04-20 Gary V. Vaughan * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the best tool so far counter rely on the tool path variable name to avoid checks for one tool being affected by the results of running the length check on a previous tool. * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional match expression argument, as different greps have different regular expression flavours. (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as literals. (AC_PROG_EGREP): Pass 'EGREP$'. (AC_PROG_GREP): Pass 'GREP$'. 2004-04-20 Albert Chin-A-Young * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable is `ac_cv_path_GREP', not `oc_cv_path_GREP'. 2004-03-29 Paul Eggert * doc/autoconf.texi (Particular Headers, Particular Types, Generic Types, Specific Compiler Characteristics, System Services, Obsolete Macros): Use 'long int', 'short int', 'unsigned int' etc. consistently instead of 'long', 'short', 'unsigned' etc. * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise. * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES): Likewise. * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise. * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T, AC_TYPE_OFF_T): Likewise. * tests/semantics.at (AC_CHECK_TYPES: backward compatibility): Likewise. * tests/foreign.at (Libtool): Create an empty aclocal.m4, to pacify libtool 1.5.2. Fix quoting problems in sed command. 2004-03-28 Paul Eggert * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE now defines HAVE_DECL_TZNAME if it is declared, when HAVE_STRUCT_TM_TM_ZONE is not defined. * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this. Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing for HAVE_TZNAME. 2004-03-28 Steven G. Johnson * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected superfluous backslashing of quotes (") in sed expressions; thanks to Paul Eggert. 2004-03-26 Steven G. Johnson * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel Fortran compiler is ifort, also added pghpf; thanks to Nelson H. F. Beebe for the bug report. 2004-03-26 Steven G. Johnson * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for quoted -cmdline argument in Portland Group compiler (bug reported by Jeffrey J. Barteet). 2004-03-25 Kevin Ryde * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to (Run Time): ... here, where it's now mentioned. 2004-03-19 Alexandre Duret-Lutz * doc/autoconf.texi (autom4te Invocation): Language Autoconf inherits from language Autoconf-without-aclocal-m4. (Customizing autom4te): Adjust example; the cache must now be disabled for language Autoconf-without-aclocal-m4. 2004-03-16 Paolo Bonzini Nathanael Nerode * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL, AC_CHECK_TOOLS): Warn if a cross-tool is found without a prefix.

Suggested by Andreas Schwab in: http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html 2003-09-26 Akim Demaille * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the directory for AC_CONFIG_COMMANDS' first argument exists. This makes valid the invocation of _AC_SRCPATH that follows.

Problem reported by Eric Sunshine in: http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html 2003-09-26 Akim Demaille The test suite are sometimes assigning timings incorrectly. Reported by Henk Krus. Diagnosed by Nicolas Joly. * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as AT_help_all. Instead of making AT_help a sequence of assignments to grow $at_help_all, just make AT_help_all be the growing contents of $at_help_all, and make a single assignment in... (AT_INIT): here. (at_times_skip): Flip the meaning and rename as... (at_times_p): this. (AT_INIT): When summarizing the test that ran, remove $at_times_file after use, and check it is present before trying to use it. 2003-09-25 Akim Demaille Version 2.57d. * bin/Makefile.am (edit): Handle '@configure_input@'. (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate) (ifnames): chmod -w. * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/ executables, not bin/ executables! Otherwise all the magic needed to find non installed files is turned off. This caused a failure of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te as found in its environment (sent by tests/autoreconf): pointing to bin/autom4te that could not find its files. * tests/mktests.sh: Force the replacement of generated files, for the sake of "mv" program that are interactive when overwriting a -w file. * config/install-sh: Upgrade from CVS Automake. 2003-09-23 Paul Eggert * doc/autoconf.texi (Limitations of Builtins): Document test -h versus test -L issues. 2003-09-23 Daniel Jacobowitz and Paul Eggert Trivial change to support GCC's configuration procedure. * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro. * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn about inconsistency if the preprocessor is set to give errors for any warning. * doc/autoconf.texi (C Compiler Characteristics): Document this. 2003-09-13 Alexandre Duret-Lutz * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm and XFile.pm from Automake. * lib/Autom4te/XFile.pm: Update from Automake. 2003-09-12 Akim Demaille Version 2.57c. 2003-09-12 Akim Demaille * config/config.guess, config/config.sub, config/missing, * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update from masters. 2003-09-12 Akim Demaille * doc/autoconf.texi (Header Portability): Promote linux/types.h, not asm/types.h. 2003-09-11 Akim Demaille * doc/autoconf.texi (Header Portability): linux/random.h.

From a suggestion by Ian Lance Taylor in . 2003-09-05 Paul Eggert * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too, for the benefit of g77 3.2. Fix suggested by Steven G. Johnson. 2003-09-04 Akim Demaille * tests/mktests.sh (ac_exclude_list): Fix the filtering of AC_FUNC_WAIT3. 2003-09-04 Akim Demaille * bin/autom4te.in: Use &fatal where more appropriate than &error. (freeze): When exiting, use $exit_code. * lib/autoconf/fortran.m4: Comment changes. 2003-09-04 Akim Demaille * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC. 2003-09-02 Steven G. Johnson Add support for newer Fortran dialects. The F77 interface is unchanged, and continues to support Fortran 77. New FC macros correspond to all the old F77 macros, with output variables FC, FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest available dialect, but older dialects can be specified. There are new macros AC_FC_SRCEXT to set the source extension, and AC_FC_FREEFORM to accept free-form source files. * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)): New macros.

(AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that are defaulted by AT_CHECK anyway. Use AT_CHECK_AUTOM4TE. * lib/m4sugar/m4sugar.m4: There should be no output at all: add a missing dnl. 2003-08-27 Akim Demaille * bin/autoheader.in: Issue the "Using auxiliary..." message only when -Wobsolete is set. Set it on by default. Suggested by Klee Dienes. 2003-08-27 Akim Demaille * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More documentation. From Guido Draheim. 2003-08-26 Akim Demaille * doc/autoconf.texi (Output): Make clear that one can run code after AC_OUTPUT. 2003-08-25 Akim Demaille * config/announce-gen, GNUmakefile, Makefile.maint: Update from CVS Bison. 2003-08-25 Alexandre Duret-Lutz * bin/autoreconf.in (parse_args): Do not pass --no-force to Automake versions prior to 1.8. 2003-08-25 Akim Demaille * doc/autoconf.texi (Header Portability): netinet/if_ether.h. From Ville Karaila. 2003-08-24 Akim Demaille * configure.ac: Bump to 2.57c. 2003-08-22 Akim Demaille Version 2.57b. * Makefile.cfg (local-checks-to-skip): New. * Makefile.maint (local-check): Rename as... (local-checks-available): this. (local-check): New. * Makefile.am (EXTRA_DIST): Add Makefile.cfg. * configure.ac: Require Automake 1.7.6. 2003-08-22 Akim Demaille Output stack traces in warnings. * lib/m4sugar/m4sugar.m4 (_m4_warn): New. Replace the former... (m4_warn): Pass the call stack to _m4_warn. * bin/autom4te.in: Adjust to output the call stack. * tests/m4sugar.at (m4@&t@_warn): Adjust. 2003-08-22 Akim Demaille * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New. * bin/autom4te.in: Adjust. 2003-08-21 Akim Demaille * lib/Autom4te/General.pm (&file_name_is_absolute): Remove. (&verbose): Remove. (&getopt): Adjust the note and verb channels, depending upon --verbose. * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in, * bin/autoupdate.in: Adjust. Use &verb, not &verbose. 2003-08-21 Akim Demaille * bin/autoheader.in (&parse_args): Use &parse_warnings and &parse_WARNINGS. ($help): Use Autom4te::ChannelDefs::usage. * bin/autoscan.in: Use Autom4te::ChannelDefs. * lib/Autom4te/General.pm: Don't export error: you don't own it. 2003-08-21 Akim Demaille First stab at preserving warnings between calls to autom4te, including when the cache is used. There are still several issues: (i) there are too many runs of m4 (one for include, one for warnings, and some more), (ii) warnings spreading on several lines are not handled gracefully, (iii) the code meant to have the call stack display for errors does not work (its handling should move from m4 to autom4te). * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs): Use them. (@preselect): Add m4_warn. ($exit_status): Remove, use $exit_code. ($help): Use Autom4te::ChannelDefs::usage. (&handle_m4): No longer define the m4_warnings. At each run, extract and report the warnings. Always cache the result, including if the exit status is on failure, since if nothing changes, we should result in the same failure, hence we can use the cache. * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse) (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn): Remove. (m4_warn): Redefine as a do-nothing: it is its invocation that matters, as warnings are now reported via traces. * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of the contents of m4_warn: make it _call_ m4_warn, so that tracing the latter reveals calls to the former. Adjust the tests. * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories. 2003-08-21 Akim Demaille * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs): Use them. 2003-08-21 Akim Demaille * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in forward order. * lib/Autom4te/ChannelDefs.pm: Doc typos. (&parse_warnings): Accept a list of warning requests. (&usage): Return a string, not a side effect. (cross): New warning category. 2003-08-21 Akim Demaille * lib/Autom4te/Configure_ac.pm (&find_configure_ac) (&require_configure_ac): Accept an optional directory argument. ($configure_ac): Remove. * lib/Autom4te/General.pm (&find_configure_ac, &canonfile) (&catfile): Remove. * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in, * bin/autoscan.in: Adjust. 2003-08-20 Akim Demaille * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'. Reported by Alexandre Duret-Lutz. 2003-08-20 Akim Demaille * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in, * bin/autom4te: Adjust. In particular, be Autoconf tools are really silent when properly working, bind the verbosity of the 'note' channel to $verbose. * lib/Autom4te/General.pm (&find_file, &mtime, &update_file) (&xsystem, &contents): Remove, since they are exported by... * lib/Autom4te/FileUtils.pm: this. More perldoc. * lib/Autom4te/General.pm (&up_to_date_p): Move to... * lib/Autom4te/FileUtils.pm: here. 2003-08-20 Akim Demaille * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New, from CVS Automake. 2003-08-20 Akim Demaille * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files) (autom4te-update): New. * Makefile.cfg (update): Bind autom4te-update. 2003-08-19 Derek Price * lib/autotest/general.m4: Comment various HELP_* diversions. (PARSE_ARGS_BEGIN): New section for option parsing related initialization. (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define package specific options and associated help. 2003-08-19 Akim Demaille * config/announce-gen, Makefile.cfg: New. * Makefile.am: Adjust. * GNUmakefile, Makefile.maint: Update from CVS Coreutils. 2003-08-19 Alexandre Duret-Lutz * lib/autom4te.in (Automake-preselections): Preselect AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include, and m4_sinclude. 2003-08-19 Alexandre Duret-Lutz * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ... (Autoconf-without-aclocal-m4): ... this new language. * doc/autoconf.texi (autom4te Invocation): Mention Autoconf-without-aclocal-m4. 2003-08-18 Derek Price * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL & RUN-IF-PASS optional arguments. 2003-08-18 Derek Price * doc/autoconf.texi (Programming in M4sh): Add doc for AS_IF. 2003-08-16 Derek Price * doc/autoconf.texi (Writing testsuite.at): Document defaults for STDOUT & STDERR arguments. 2003-08-14 Derek Price * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print DESCRIPTION rather than FILE and LINE. Shorten result to fit in new, shorter column three. Add DESCRIPTION to log file content. 2003-08-13 Derek Price * lib/autotest/general.m4 (AT_INIT): Correct typo in final status output. 2003-08-12 Derek Price * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API. (AT_CHECK_NOESCAPE): Move core functionality to... (_AT_CHECK): ...this new macro. 2003-08-07 Derek Price * lib/autotest/general.m4 (AT_CHECK): Move core functionality... (AT_CHECK_NOESCAPE): ...to this new macro. 2003-07-31 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in Bash 2.01. Problem reported by Brian Gough in . 2003-07-25 John W. Eaton * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore -lcrt1.o, for OS X. (trivial change) 2003-07-07 Paul Eggert * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...' inside '#ifndef __cplusplus'. Problem reported by Bob Friesenhahn. 2003-07-06 Bill Clarke * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to 'long', not 'int', for benefit of Sun's recent C++ compilers (trivial change). See: http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html (This really should be 'intptr_t', not 'long', but that would take more work.) 2003-06-25 Akim Demaille * lib/Makefile.am (autom4te.cfg): Make it read only. Depend on Makefile since it contains substitutions. From Paolo Bonzini. * lib/autom4te.in (args): Add local.at? for Autotest args. This change was made on autom4te.cfg which is generated. Reported by Raja R. Harinath. 2003-06-25 Akim Demaille * doc/autoconf.texi (Header Portability): sys/mount.h. From Gareth McCaughan. 2003-06-23 Akim Demaille * lib/autotest/general.m4 (AT_INIT): Report a single config.log, not all of them. This fixes 1. the fact that when testing Autoconf there are many many config.log, 2. the incorrect use of top_srcdir to find config.log. Don't mix the detailed output of failed test with the summary of failures. Rather, append detailed log afterwards. 2003-06-23 Akim Demaille * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being always run: output config.log on $at_group_log. 2003-06-23 Akim Demaille * tests/torture.at (#define header templates): Don't use quotes in C++ comments as it puzzles Emacs' sh font-lock-mode. 2003-06-23 Akim Demaille * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice. * lib/autom4te.cfg (args): Add local.at? for Autotest args. * tests/atspecific.m4: Rename as... * tests/local.at: This. * tests/suite.at: Move the globals into... * tests/local.at: here. * tests/Makefile.am: Adjust. * doc/autoconf.texi (testsuite Scripts): Adjust. 2003-06-21 Kevin Ryde * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby ensuring we add -std1 for full-ANSI. * doc/autoconf.texi (hdrindex): New macro. Add index entries for portability of various standard header files. 2003-06-20 Akim Demaille * configure.ac: Bump to 2.57b. 2003-06-20 Akim Demaille Version 2.57a. 2003-06-20 Akim Demaille * bin/autom4te.in: Don't rely on $HOME being defined.

(xqx, xsystem): Use handle_exec_errors. 2003-05-23 Alexandre Duret-Lutz * lib/Autom4te/General.pm (END): Rewrite exit code processing. Do not call `_exit()', simply modify `$?'. (xsystem): Reset $! before running system, and check it afterward. * tests/tools.at (autoupdating AC_PREREQ): Expect exit status 63 for version mismatches. 2003-05-23 Akim Demaille * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in the middle of a line). * lib/m4sugar/m4sugar.m4: Likewise. Remove useless spaces in comments. 2003-05-23 Akim Demaille * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an exit 63, so that we (or Automake's "missing") can tell the difference with a plain failure. * doc/autoconf.texi (Notices): Adjust. 2003-05-23 Akim Demaille * Makefile.am, bin/Makefile.am, config/Makefile.am, * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am: White spaces cleanup. 2003-05-22 Jim Meyering Paul Eggert * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Remove `#include ' from the list; we should never make confdefs.h include or , because the resulting namespace pollution would cause other tests to fail. Configure scripts run with some older versions of g++ and HP's aCC would fail due to such an #include. Problems reported by Matthew Mueller in and by Keith Bostic in . In the test, use the test declaration before including , as that's closer to how it'll be used. 2003-05-23 Akim Demaille * doc/autoconf.texi (Header Portability): ucred.h. From Ian Redfern. 2003-05-22 Paolo Bonzini Overhaul Autotest's logging: generate separate log files in testsuite.dir/NNN/testsuite.log, and append them to testsuite.log instead of re-running the test verbosely. * lib/autotest/general.m4 (AT_INIT): Use a single redirected file descriptor, write 0 to at_status_file instead of setting at_status=0, initialize some new variables (at_status_file, at_group_log, at_suite_log, at_tee_pipe). Remove the cruft to rerun the tests, instead append the at_group_log to the at_suite_log when a test fails. (AT_SETUP): pipe the test case's output into at_tee_pipe, with the AS_MESSAGE_LOG_FD redirected to stdout. (AT_CLEANUP): save the output status in $at_status_file and restore it, redirect the AS_MESSAGE_LOG_FD back to its original place. (AT_CHECK): since tests are run with a redirected stdout, and used to be re-run in verbose mode, turn some $at_verbose into echo, and don't redirect the output of testing stdout and stderr. * lib/autotest/autoconf.texi (testsuite Scripts): Update the name of the debugging directory and information about its contents. 2003-05-22 Paolo Bonzini * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd parameter. 2003-05-22 Akim Demaille * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4 * lib/autoconf/fortran.m4 lib/autoconf/general.m4 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4 * lib/autoconf/status.m4: Fix and adjust copyright notices. 2003-05-22 Akim Demaille * aclocal.m4, bin/autoconf.as, lib/autoconf/autoconf.m4, * lib/autoconf/autoheader.m4, lib/autoconf/autoupdate.m4, * lib/autoconf/c.m4, lib/autoconf/fortran.m4, * lib/autoconf/general.m4, lib/autoconf/headers.m4, * lib/autoconf/lang.m4, lib/autoconf/libs.m4, * lib/autoconf/programs.m4, lib/autoconf/specific.m4, * lib/autoconf/status.m4, lib/autoconf/types.m4, * lib/autotest/general.m4, lib/m4sugar/m4sugar.m4, * tests/atspecific.m4, tests/base.at, tests/compile.at, * tests/foreign.at, tests/m4sh.at, tests/semantics.at, * tests/tools.at, tests/torture.at: Whitespace clean up.

Discuss NetBSD, FreeBSD, OpenBSD, and Tru64 make in the "target lookup" section. (Automake): Automake 1.5+ no longer requires special tools to be present on the developer's host. 2003-02-26 Richard Dawe * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set to a shell that can handle redirection or quoting correctly.

This should fix the bug reported by Momchil Velkov in . * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for obsolete AC_CHECK_TYPE. The missing empty arg was reported by Simon Josefsson in . * Makefile.maint (www-gnu): New macro.

Reported by Ezra Peisach. 2002-11-05 Akim Demaille * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD): Remove. We _have_ to stop using the old compatibility scheme that tried to avoid useless backslashes because Libtool 1.4.3 contains a AC_DEFINE([error_t], [int], [Define to a type to use for \`error_t' if it is not otherwise available.]) We _have_ to quote the single quote and backslashes with \. The old compatibility scheme saw that ` was backslashed, and therefore did not quote the single quote. Hence before this patch, Autoconf was not compatible with Libtool. 2002-11-04 Paul Eggert * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables, too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY, LC_NAME, LC_PAPER, LC_TELEPHONE. * doc/autoconf.texi (Special Shell Variables): Mention those vars. 2002-11-04 Akim Demaille Version 2.54c. * Makefile.maint (update, cvs-update, po-update, do-po-update): New. * config/texinfo.tex: Update. 2002-11-03 Akim Demaille * bin/autoreconf.in (&autoreconf_current_directory): New, extracted from...

Suggested by Tim van Holder. 2002-10-29 Paul Eggert * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and AC_FUNC_REALLOC check for compatibility with glibc, not POSIX. Problem reported by Bruno Haible. 2002-10-29 Akim Demaille * doc/autoconf.texi (Header Templates): Put also in words what the pictures says to assist free style readers. (Customizing autom4te): s/--cache=/--cache /. 2002-10-29 Akim Demaille * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and sys/wait.h. sparc_address_test returns void. Use it with an argument, as prototyped. From Bruno Haible. 2002-10-29 Akim Demaille * doc/autoconf.texi (Subdirectories): Cygnus dirs have configure.in, not configure.ac.

(ansi2knr.c-url_prefix): Remove. 2002-10-16 Akim Demaille Because of caching, some files that no longer exist and are no longer required can still cause errors. Reported by Alexandre Duret-Lutz. * bin/autom4te.in (&parse_args): Do not prepend `--reload-state' to frozen files in @ARGV, as @ARGV must remain being a list of files. Rather, at M4 call sites, use this... (&files_to_options): New function. (&freeze): Use &error. (&up_to_date): If a file that was included according to the cache is no longer there, then the output is out dated. (&main): Don't even check whether a file is up to date is anyway --force is given. * tests/tools.at (autom4te cache): New. 2002-10-16 Akim Demaille * bin/autoconf.as: Kill dead options. * bin/autoupdate.in (&parse_args): Kill old options. * bin/autoreconf.in (&parse_args): Remove dead options. Factor some code. (&autoreconf): Report the directories we enter *and leave*, so that error messages can be easily located, and use GNU Make format, so that Emacs' compile mode understands us. * lib/Autom4te/General.pm (&update_file): Use `verbose' to report if some file was changed instead of `print'. * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed. (&parse_args): Remove the dead options. * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new autoheader's quiet mode.

From Sam Varshavchik. 2002-10-08 Akim Demaille * bin/autoreconf.in (&autoreconf): Run autopoint before the first aclocal invocation, as Gettext macros might not be visible to aclocal. Instead of blindly running autopoint, scan configure.ac (not the traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does. Reported by Paul D. Smith. 2002-10-08 Paul Eggert Work around problems found when POSIXLY_CORRECT=1 is set. None of this seems to have anything to do with POSIX, really, but it's how Perl getopt works. * bin/autom4te.in (parse_args): Configure GetOpt with "permute", too. * doc/autoconf.texi (Invoking autom4te): --warning -> --warnings. * lib/autom4te.in: --warning -> --warnings. 2002-09-28 Akim Demaille * doc/autoconf.texi (autom4te.cache): New section. 2002-09-28 Akim Demaille * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections) (Automake-preselections): Update. * bin/autoreconf.in, bin/autoheader.in: Comment changes. 2002-09-28 Akim Demaille * lib/autoscan/autoscan.pre: Move all the remaining rules to... * lib/autoconf/c.m4, lib/autoconf/functions.m4, * lib/autoconf/headers.m4, lib/autoconf/libs.m4, * lib/autoconf/specific.m4, lib/autoconf/types.m4: here. 2002-09-28 Akim Demaille * tests/torture.at (Configuring subdirectories): Be robust to users who use config.site to require for a cache: in this case, the two last configure runs, using two different sets of arguments, trigger a legitimate error. 2002-09-28 Akim Demaille * tests/m4sh.at (Functions Support, Functions and return Support): New. 2002-09-28 Akim Demaille * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and autoheader are Perl programs.

(autoscan.pre): New file. 2002-09-28 Akim Demaille * bin/autoscan.in (@kinds): Make them singular. Adjust all uses. (&init_tables): When --debug, report the list of rules to ease tracking changes in autoscan.list. * lib/autoscan/autoscan.list (function): Strip comments, sort. 2002-09-28 Akim Demaille * lib/autoscan/functions, lib/autoscan/headers, * lib/autoscan/identifiers, lib/autoscan/makevars, * lib/autoscan/programs: Merge into... * lib/autoscan/autoscan.list: this. * bin/autoscan.in (&init_tables): Adjust. 2002-09-28 Akim Demaille * lib/autoscan/functions, lib/autoscan/headers, * lib/autoscan/identifiers, lib/autoscan/makevars, * lib/autoscan/programs: Make the `kind' explicit, i.e., each `functions' line is now prefixed with `function:'. * bin/autoscan.in (&init_tables): Adjust. 2002-09-28 Akim Demaille From now on, autoscan files must always map a macro name to a word: there is no `default' macro for autoscan. * bin/autoscan.in (&init_tables): Reject entries with no macro at all. * lib/autoscan/functions, lib/autoscan/headers: Make the macro explicit. 2002-09-28 Akim Demaille * bin/autoscan.in (%c_keywords): Remove.

Mention libtool 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug. 2002-09-24 Paul Eggert Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8 make handles suffix-rules differently from GNU make. * bin/Makefile.am (SUFFIXES, .in): Remove. (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te): Move the body of the old .in rule here. 2002-09-16 Akim Demaille i960 compilers create `b.out' files by default. Reported by Ralf Corsepius. * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files. (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out. 2002-09-13 Paul Eggert * doc/autoconf.texi (Particular Headers): Remove obsolete reference to `struct timezone' in the description of AC_HEADER_TIME. 2002-09-13 Akim Demaille Version 2.54. * config/config.sub, config/config.guess: Update. * Makefile.maint: Update from bits of the Coreutils 4.5.1. * Makefile.am: Adjust. 2002-09-13 Akim Demaille * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest reading config.log when the compiler is rejected. Suggested by Guido Draheim. 2002-09-13 Akim Demaille * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals (chdir_init) might hang when stat'ing mounted directories. Reported by Vance Shipley. 2002-09-12 Akim Demaille * bin/autoscan.in (&parse_args): Pass a reference to the lists, not the lists. 2002-09-12 Akim Demaille * doc/autoconf.texi (Defining Symbols): Present two different prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the difference between 1 argument calls, and 2-3 argument calls. 2002-09-12 Peter Eisentraut * doc/autoconf.texi: Review grammar and punctuation. 2002-09-11 Paul Eggert * doc/autoconf.texi: Fix minor formatting, spelling, and grammatical typos. (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case is obsolescent. 2002-09-11 Akim Demaille * doc/autoconf.texi (Questions): Rename as... (FAQ): this. (Defining Directories): New. 2002-09-09 Akim Demaille * doc/autoconf.texi (Making testsuite Scripts): Update. Suggested by Nishio Futoshi. 2002-09-09 Koji Arai * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a plain `@' is wanted. 2002-09-09 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the `duplicates', since the algorithm was too naive and could keep `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and keep `--prefix foo --prefix bar' as `--prefix foo bar'. Reported by Ralf Corsepius. * tests/torture.at (Configuring subdirectories): Exercise these cases. 2002-09-09 Akim Demaille * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when looking for a replacement file. * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the directory is relative. * doc/autoconf.texi (Generic Functions): Clarify the replacement directory definition. Reported by Andreas Schwab and Jim Meyering. 2002-09-06 Akim Demaille * doc/autoconf.texi (Setting Output Variables): Clarify what precious variables are. Suggested by Pontus Skoeld. 2002-09-05 Akim Demaille * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate) (ifnames, autoscan, autom4te): Since we don't only depend on configure.ac variables (such as VERSION etc.), but also on prefix and so forth, depend on Makefile, not configure.ac. Reported by Alexandre Duret-Lutz. * doc/autoconf.texi (Installation Directory Variables): Adjust. 2002-09-05 Kevin Ryde * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes doesn't seem to be confined to ia64, just say "some versions". 2002-09-04 Akim Demaille * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by Automake 1.6c. * Makefile.am (maintainer-clean-local): Remove. (MAINTAINERCLEANFILES): Remove COPYING. 2002-09-03 Paul Eggert * doc/autoconf.texi (Configuration Commands): Remove obsolete example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus Brinkmann. 2002-09-03 Akim Demaille * configure.ac: Bump to 2.53d. * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake as of today, on Automake's team suggestion. 2002-09-03 Akim Demaille Version 2.53c. 2002-09-02 Akim Demaille * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and SITE_MACRO_DIR. * configure.ac: Disable SITE_MACRO_DIR. 2002-09-02 Jim Meyering * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/, i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios. Also, tweak grammar: s/make sure to/be sure to/. 2002-09-02 Paul Eggert * doc/autoconf.texi (Limitations of Builtins): Explain why logical directory names are generally preferable to physical names. 2002-09-02 Akim Demaille * lib/Autom4te/General.pm (&update_file): s/die/error/. Reported by Raja R. Harinath. * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in, * bin/autoupdate.in: Use error instead of die. 2002-09-01 Paul Eggert * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use ordinary shell concatenation rather than echo+tr+sed command that runs afoul of a long-line-related sed bug in Solaris 8. * bin/autoheader.in (parse_args): --warning -> --warnings. * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to stdout, as traditional "ls" does. * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O): Likewise. * doc/autoconf.texi (Limitations of Usual Tools): Add "ls". * bin/autoconf.as: Add --prepend-include option. This patch was applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth, but bin/autoconf.in is generated automatically from bin/autoconf.as. * bin/autoconf.in, configure: Regenerate. * doc/autoconf.texi (Special Shell Variables): Mention ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL, MAILPATH and set PS1, PS2, PS4 to default values, to work around bug in pre-3.0 UWIN ksh reported by Bruce Lilly. For LC_ALL etc, first try to set to "C" as POSIX requires and as the Autoconf documentation specifies; fall back to "unset" only if this fails. Use a shell for-loop for this rather than an m4 loop, to shorten the output script. 2002-08-30 Paul Eggert * doc/autoconf.texi (Special Shell Variables): Mention POSIX 1003.1-2001's requirements for CDPATH. Give a simpler workaround for the CDPATH problem. Document PWD. (Limitations of Builtins): Document the problem that "cd $foo" and "ls $foo" may refer to different directories in shells conforming to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset" example, since the old example is now out of date. * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd FOO" and "ls FOO" talk about different directories; this catches problems when POSIX 1003.1-2001 "cd" fails due to symlink spaghetti. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead of rolling our own unset. (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since in practice we needn't worry about CDPATH if unset doesn't work. * Makefile.in, aclocal.m4, bin/Makefile.in, config/Makefile.in, doc/Makefile.in, lib/Makefile.in, lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in, lib/autoscan/Makefile.in, lib/autotest/Makefile.in, lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in, tests/Makefile.in: Regenerate with Automake 1.6.3. * config/config.guess, config/config.sub, config/mkinstalldirs: Update. * configure: Regenerate with self. 2002-08-30 Kevin Ryde * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc" default output. 2002-08-29 Rainer Orth * bin/autom4te.in (Request::load): Correctly test for "do" read failure. 2002-08-29 Akim Demaille * lib/Autom4te/General.pm (&xqx): New. (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by hand, which is not portable. (&error): New. * bin/autom4te.in: Use them. Use &error instead of die. * tests/m4sugar.at (m4_warn, m4_require: circular dependencies): Adjust. 2002-08-17 Paul Eggert * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the default list of compilers to try, since it was long ago superseded by the ksh fc builtin. Suggested by Steven G. Johnson. 2002-07-31 Alexandre Duret-Lutz * doc/autoconf.texi (Invoking autom4te): End the option table, fixing a bug introduced by the previous patch. (Limitations of Make): Add a 'target lookup' subentry in the 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'. 2002-07-29 Mark D. Roth * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir options and use $AUTOM4TE_PATH. * doc/autoconf.texi: Remove documentation of autom4te --include-envvar and --site-macro-subdir options and document use of $AUTOM4TE_PATH. * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir arguments from each language section. 2002-07-29 Paul Eggert * doc/install.texi: Include copyright symbol in copyright notice. * Makefile.am (MAKEINFO): Remove; it's a user-specified macro. Replace with: (AM_MAKEINFOFLAGS): New macro. * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise. * Makefile.am (INSTALL): Use the new macros. Use -o rather than --output, since "missing" does not grok --output. 2002-07-25 Alexandre Duret-Lutz * doc/autoconf.texi (Limitations of Make): Escaped newlines in comments do not always work. Never trust the exit status of `make -k'. 2002-07-24 Kevin Ryde * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts): Untabify, since tabs are not enjoyed by texi2dvi and makeinfo. 2002-07-23 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002 apparently treats PATH="nonexistent" as if it contained ".". Bug reported by Stefan `Sec' Zehl. 2002-07-22 Alexandre Duret-Lutz * doc/autoconf.texi (Limitations of Make): Mention the special handling of the obj/ directory by BSD make. 2002-07-20 Kevin Ryde * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing backslashes. 2002-07-19 Akim Demaille * doc/autoconf.texi (Function Portability): `exit'.

Bug reported by Sergey Poznyakoff. This improves on an earlier suggestion by H. Peter Anvin. 2002-05-16 Paul Eggert AC_FUNC_FNMATCH now tests only for POSIX compatibility. AC_FUNC_FNMATCH_GNU also tests for GNU extensions. Both macros now accept an optional source-dir arg. New macro AC_GNU_SOURCE to define _GNU_SOURCE. * NEWS: Document this. * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise. * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro. (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance, not for GNU extensions; this undoes part of the 2000-11-03 change, reverting to 2.13-compatible behavior. Add new optional argument DIR.

The test is unnecessary, and it causes a 'test' syntax error if it fails. Bug reported by Stephen Gildea. * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED): If prototypes are supported, use them to check this at compile-time, instead of trying to check it at run-time. If we must do a run-time check, assume that setvbuf is standard when cross-compiling, as nonstandard setvbuf occurs only on ancient and unlikely hosts. Bug reported by Paul D. Smith. * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional argument specifying location of getloadavg.c. This removes a FIXME. This idea was taken from Jim Meyering's implementation in textutils. * doc/autoconf.texi (Particular Functions): Document this. Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since that's what the code does; this fixes a bug reported by Paul D.

Also, sleep 1 second after the first aclocal, to work around problems with sub-second time stamps on the input files. 2002-04-29 Thien-Thi Nguyen * doc/autoconf.texi: Mention "set -e -x" lossage under node "Limitations of Builtins". 2002-04-29 Akim Demaille * doc/install.texi: Better wording for setting variables when running configure. From Christian Cornelssen. 2002-04-29 Akim Demaille * tests/m4sh.at (LINENO): If testsuite itself is rewritten because of lack of $LINENO support, then the test will compare the $LINENO in testsuite vs. the lineno in the test file. This is wrong, of course. Be sure to protect it. Reported by Patrick Welche. 2002-04-25 Akim Demaille * doc/autoconf.texi (Obsolete Macros): Typo. Reported by Vladimir Volovich. 2002-04-25 Akim Demaille * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older than some of the input files, hence, on the second run of aclocal, if some of its input are younger, make them older. Suggested by Paul Eggert. 2002-04-25 Akim Demaille * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

Now it also works for shell variables. 2002-02-07 Akim Demaille * doc/autoconf.texi (Limitations of Builtins): More about case/esac. 2002-02-06 Akim Demaille * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty case/esac, some shells don't support it. Reported by Zack Weinberg. * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New. 2002-02-06 Akim Demaille * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be sure not to introduce newlines in at_groups. * lib/autotest/Makefile.am (autotest.m4f): Typo. 2002-02-06 Akim Demaille * tests/torture.at (Configuring subdirectories): Skip if aclocal is not available. 2002-02-05 Paul Eggert * doc/autoconf.texi (Specific Compiler Characteristics): Describe HP-UX cc bug workaround more accurately. * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long, not unsigned long. * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC cross-compilers, too. This undoes some of the most recent change to this file. 2002-02-05 Akim Demaille * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS, to make sure they are up to date when `check' is run. 2002-02-05 Akim Demaille * doc/autoconf.texi (Making testsuite Scripts): Document package.m4. 2002-02-05 Akim Demaille * lib/freeze.mk: New. 2002-02-05 Akim Demaille Implement `autom4te --freeze'. * bin/autom4te.in (&freeze): New. * lib/autoconf/autoconf.m4, lib/autotest/general.m4, * lib/m4sugar/m4sh.m4: Don't include files given by autom4te. 2002-02-05 Akim Demaille * bin/autom4te.in (&parse_args): Implement `frozen files are optional are the sum of the previous files on the command line'. Also, pass `--reload-state=' on them, so... (handle_m4): don't. * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh. (M4sh): Rely on M4sugar. (Autotest, M4sh, M4sugar): Use frozen files. 2002-01-31 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4. * doc/autoconf.texi (Initializing configure): Adjust. 2002-01-30 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non alphanumeric to `-' instead of `_'. 2002-01-30 Akim Demaille * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one for plain code, the other for cross-compilation code. The latter is now run with GCC only. * doc/autoconf.texi (Compilers and Preprocessors): New. 2002-01-30 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined values. * doc/autoconf.texi (Initializing configure): Explain how to change AC_INIT default values. 2002-01-29 Akim Demaille * tests/torture.at (Configuring subdirectories): Use configure.in, so that aclocal 1.4 works. Reported by Alexandre Duret-Lutz and Larry Schmitt. 2002-01-28 Akim Demaille * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer needs an argument. 2002-01-28 Akim Demaille * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust AUTOTEST_PATH *after* it was set. Don't put `.' in the PATH: the user should be precise and `./' if needed. In addition, given that the test suite does some `cd', if `.' is in the path, the `tested programs' sections will report programs found in the test suite's directory, while during the tests (performed in their own directory), these programs are no longer visible. In other words, the results is confusing and useless. * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH. 2002-01-24 Akim Demaille Version 2.52g. 2002-01-24 Akim Demaille * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in, * doc/autoconf.texi: Finally add Akim as an author. 2002-01-24 Akim Demaille * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR. (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be Bourne. Use /bin/sh. From Andreas Buening. 2002-01-24 Akim Demaille * config/config.guess, config/config.sub, config/texinfo.tex: Update from masters. 2002-01-24 Akim Demaille * Makefile.am (AUTOMAKE_OPTIONS): 1.5b. * config/auxdir.m4, config/cond.m4, config/depend.m4, * config/init.m4, config/install-sh.m4, config/lispdir.m4, * config/missing.m4, config/sanity.m4, config/select.m4, * config/strip.m4: Remove, to ease sync'ing with any version of Automake. 2002-01-24 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS) (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

(Particular Functions): Document AC_FUNC_STRNLEN. * lib/autoscan/functions: Adjust. 2002-01-06 Akim Demaille * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create package.m4, since is really depends upon configure.ac, not configure. * doc/autoconf.texi (testsuite Scripts): Adjust. * tests/Makefile.am (package.m4): New. EXTRA_DIST it since its a source. 2002-01-06 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING, and PACKAGE_BUGREPORT from here... (_AC_INIT_DEFAULTS): to here, since it is unrelated to the arguments. (_AC_INIT_PREPARE): AC_DEFINE these symbols. * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*. (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'. * tests/tools.at (autoheader): Adjust. * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust. 2002-01-06 Akim Demaille * bin/autoscan.in (scan_file): Use `&used'. 2002-01-03 Akim Demaille * doc/autoconf.texi (Output): Improved wording regarding use of AC_OUTPUT. From Olly Betts. 2001-12-18 Kevin Ryde * doc/autoconf.texi (Function Portability): Add notes on sscanf sometimes needing writable input. 2001-12-17 Jim Meyering * doc/autoconf.texi (New Macros): Tweak wording. 2001-12-14 Akim Demaille * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the trailing files, don't apply `-rf' to files which might not be created by configure (core, core.*, and *.core), but just `rm -f'. Suggested by Jonathan Kamens. 2001-12-14 Aaron M. Ucko * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'. 2001-12-14 Akim Demaille * Makefile.am (MAINTAINERCLEANFILES): Remove configure. 2001-12-13 Peter Eisentraut * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to abs_builddir, top_buildpath to abs_top_builddir, srcpath to abs_srcdir, top_srcpath to abs_top_srcdir. (_AC_OUTPUT_FILES): Adjust. * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4, * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at, * tests/wrappl.in, tests/wrapsh.in: Adjust. 2001-12-12 Steven G. Johnson * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed C/Fortran linking on HP/UX, by extracting the Fortran library search path from the LPATH line in the $F77 -v output. 2001-12-12 Kevin Ryde * doc/autoconf.texi (File Descriptors): Use a clearer layout for the forbidden file descriptors table. 2001-11-26 Akim Demaille * bin/autoscan.in (%c_keywords): Build it at top level. Map to 1 in order to simplify its uses. 2001-11-26 Akim Demaille * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile): Remove $filepath, useless. (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@ variables, they are really part of the tokens. Split the input line on spaces and then look for tokens. Now autoscan ceases to ask for AC_PROG_LEX for the package Bison because of `lex$U.$(OBJEXT)'. (&scan_files): Use "@list" instead of join. * doc/Makefile.am (CLEANFILES): Add *.fns. 2001-11-26 Akim Demaille * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in: Remove, replaced by... * tests/wrappl.in: Be common for all the Perl executables. In particular autoscan and autoheader want -I. * configure.ac: Adjust. * lib/autoscan/headers: errno.h is portable. 2001-11-26 Akim Demaille * bin/autoscan.in (used): New. Use it. 2001-11-26 Akim Demaille * bin/autoscan.in (&scan_c_file): Better parsing of CPP directives. (&scan_sh_file): Remove a duplicate pattern. (&check_configure_ac): Use long options. * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA. 2001-11-26 Akim Demaille * bin/autoscan.in (scan_c_file): Fix the handling of C comments. Before, having a line containing the opening of a multi line comment made the whole line be ignored. 2001-11-26 Akim Demaille * doc/autoconf.texi (Using an Autotest Test Suite): New. (testsuite Scripts): Be one of its subsection. (Autotest Logs): New. 2001-11-26 Akim Demaille Test groups are now run two directories deeper. * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir, top_srcdir and top_builddir with at_srcdir, at_top_srcdir and at_top_builddir. * lib/autotest/general.m4 (AT_INIT): Compute srcdir, top_srcdir, builddir and top_builddir. Use `at_*dir' relatively to the directory containing the suite, use `*dir' when relatively to the current group dir. 2001-11-25 Joseph S. Myers * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4, lib/autoconf/functions.m4, lib/autoconf/headers.m4, tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix spelling errors. 2001-11-22 Alexandre Duret-Lutz * doc/autoconf.texi (Using System Type): Add an example of `case $host' usage so people quit using `case $target' everywhere. 2001-11-22 Akim Demaille * doc/autoconf.texi (Installation Directory Variables): Englishoes spotted by Jim Meyering. 2001-11-16 Paul Eggert This patch implements a `long double' suggestion by Oliver Kiddle. * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array static, to catch errors if the value isn't known at compile-time and the compiler supports dynamic arrays. Change its name from `_array_' to `test_array' to avoid potential name clashes. (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time test. Do not define HAVE_LONG_DOUBLE if `long double' is no better than double. Catch a bug in GCC 2.95.2 x86. * doc/autoconf.texi (C Compiler): Document the above. * NEWS: Likewise. 2001-11-13 Akim Demaille * tests/m4sh.at (LINENO): Protect from autom4te's substitution by hand. * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does. 2001-11-13 Akim Demaille * lib/autotest/general.m4 (AT_INIT): After having run the test group, go back to the initial directory, not to at_suite_dir. 2001-11-13 Akim Demaille * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH) (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te. (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include option. (AT_CHECK_CONFIGURE): Use absolute paths. (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it. The problem is still the old one: there is no means in M4 (that I know about) to create a defining macro, because there is no means to create `$1' etc., therefore, the defining macro ``swallows'' all the arguments meant to the defined macro. 2001-11-13 Akim Demaille * tests/atspecific.m4 (AT_DATA_AUTOCONF): New. (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in configure.ac. * tests/aclocal.m4: Remove, as it is no longer used. 2001-11-13 Akim Demaille * lib/autotest/general.m4: Change `tests?' into `groups?' in variable names when referring to a single test group, or to `suite' when referring to the whole test suite. `at_last_test' is removed: m4 compute at_format itself. (at_stdout, at_stder1, at_stderr): New variables. (AT_CHECK): Use them. 2001-11-13 Akim Demaille * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative, in PATH. Create `testsuite.dir/003/run' instead of `testsuite.003'. Do it as soon as a test fails, don't wait till the end of the test suite. Don't remove $as_me.[0-9]*, since these files no longer exist. 2001-11-13 Akim Demaille * tests/tools.at: Use absolute paths, since we are no longer run in place. 2001-11-13 Akim Demaille Now that tests are running in their own private dir, there is no need to list the files to remove at the end of tests groups. * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES): (AT_data_files, at_data_files): Remove. (AT_CLEANUP, AT_DATA): Simplify. (AT_INIT): Adjust. Remove the group dir if !debug && !failed. * tests/atspecific.m4: Adjust. 2001-11-13 Akim Demaille Start a new layout for Autotest: `testsuite' creates `testsuite.dir' in which the at-check-line etc. files are to be found, and `testsuite.dir/003' where the test group 3 is run. * lib/autotest/general.m4 (AT_INIT): at_tests_dir, at_check_line_file, at_format, at_test_normalized, at_group_dir are new variables. Create the directories. Use absolute paths for at- files. (AT_CHECK): Adjust. 2001-11-11 Michael Matz * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic. (m4_car2): New. (m4_car): Properly quote arguments. 2001-11-13 Akim Demaille * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope with stricter rules on LIBOBJS. 2001-11-12 Paul Eggert * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too. * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines __PROTOTYPES too. 2001-11-12 Akim Demaille * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS. 2001-11-12 Akim Demaille * lib/autoconf/c.m4, lib/autoconf/fortran.m4, * lib/autoconf/functions.m4, lib/autoconf/general.m4, * lib/autoconf/headers.m4, lib/autoconf/libs.m4, * lib/autoconf/programs.m4, lib/autoconf/specific.m4, * lib/autoconf/types.m4: When invoking AC_DEFINE and friends, specify to what the macro should be defined (typically to 1). 2001-11-12 Akim Demaille * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB. From Jim Meyering. 2001-11-12 Akim Demaille * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the definition used by Automake where LEX is +/- "${missing} lex" and `missing' itself contains variables. 2001-11-12 Akim Demaille * lib/autotest/general.m4 (AT_INIT): Push KILL at the end. Now that M4sh pushes BODY, the comments were output at the end of the test suites. 2001-11-08 Akim Demaille * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so that we can trace macros from aclocal.m4. Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is obsoleted, and redirect to the former anyway. Reported by Ralf Corsepius. 2001-11-08 Akim Demaille * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be processed only if present. * tests/torture.at (Configuring subdirectories): Use autoreconf instead of successive calls to autoconf. Add a nonexistent subdirectory to exercise the patch above. Reported by Ralf Corsepius. 2001-11-08 Kevin Ryde * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc doesn't accept .S files. 2001-11-07 Akim Demaille * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2. * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS. (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/. * bin/autom4te.in (warn_forbidden): New. (handle_output): Use it. Read m4_pattern_forbid with messages. 2001-11-05 Akim Demaille * bin/autom4te.in (--normalize): Remove. * lib/autom4te.in: Adjust. 2001-11-05 Akim Demaille * tests/Makefile.am (testsuite): Rename this target as... ($(TESTSUITE)): this. From Nicolas Joly. 2001-11-05 Alexandre Duret-Lutz * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing the --prefix option, also remove it's argument. 2001-11-05 Akim Demaille * doc/autoconf.texi (testsuite Invocation): Update. (Writing testsuite.at): Update. 2001-11-03 Akim Demaille * doc/autoconf.texi: s/@code/@command/ where appropriate. 2001-11-03 Akim Demaille * lib/Autom4te/General.pm: (&catfile, &canonfile) (&file_name_is_absolute): New, wrappers around routines from File::Spec. Use and export them. (&find_configure_ac): Optionally take a directory where to look at. * bin/autoreconf.in (&parse_args): Trim the configure.ac part of the arguments. Default @ARGV to `.', not find_configure_ac. (&autoreconf): Argument is a directory. Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing. * doc/autoconf.texi (autoreconf Invocation): Update. 2001-11-03 Akim Demaille * lib/Autom4te/General.pm (@export_vars, @export_subs) (@export_forward_subs): New. Add basename, dirname, and fileparse. (@EXPORT): Adjust. * bin/autoreconf.in (&autoreconf): Fix call to fileparse. Don't look for aclocal flags if we already know aclocal is not used. Move aclocal.m4t only if it exists. Reported by Ezra Peisach. 2001-11-03 Akim Demaille * bin/autoreconf.in (&parse_args): Work only on the configure.ac passed on command line, defaulting to ./configure.ac if present. (&maybe_autoreconf, File::Find): Remove, unused. (&autoreconf): If autoconf is not used, don't try to trace. 2001-11-02 Akim Demaille * configure.ac: Bump to 2.52g. 2001-11-02 Akim Demaille Version 2.52f. 2001-11-02 Akim Demaille * config/config.guess, config/config.sub, doc/standards.texi: * config/lispdir.m4: Update from masters. * configure.ac: Bump to 2.52f. 2001-11-02 Akim Demaille * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''. Don't run aclocal when aclocal.m4 is not from aclocal. From Ezra Peisach. Don't run libtoolize and gettextize if --install is not given. 2001-11-01 Paul Eggert * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to be invoked before _AS_LINENO_PREPARE. (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather than character ranges. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before invoking AS_BASENAME. Set the locale variables to 'C' if possible, as POSIX requires this to get the traditional behavior. * doc/autoconf.texi (Special Shell Variables): Describe the above. 2001-10-31 Paul Eggert * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body with {}, as that triggers a bug in Bash 2.05. (_AS_LINENO_PREPARE): Use Sed rather than Awk. Fix the sed prepass to work even if there are multiple instances of $LINENO on the same line. Do not substitute for other variables like $LINENOT. Do not check file dates; such a check is unreliable on sufficiently fast machines, and removing the check makes the code simpler and more reliable. Check for output and chmod failures. * doc/autoconf.texi (Special Shell Variables): Document the above. 2001-10-31 Akim Demaille * tests/Makefile.am (atconfig): Remove this target, Automake handles it now. 2001-10-31 Akim Demaille * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be provided, while it is optional. * configure.ac: Adjust. 2001-10-26 Paul Eggert * NEWS, README, configure.ac, lib/Autom4te/General.pm, lib/Autom4te/Struct.pm: Require Perl 5.005_03 instead of just 5.005, as some tests fail with 5.005_02. * doc/autoconf.texi (Special Shell Variables): Document some more LINENO gotchas, particularly with respect to the Awk+Sed hack. * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro. (_AS_LINENO_PREPARE): Use it instead of shell eval, since eval $LINENO is not portable in practice. 2001-10-24 Akim Demaille * lib/Autom4te/General.pm (backname): New. 2001-10-24 Akim Demaille * m4/: Remove, merged into... * config/: here. 2001-10-23 Tim Van Holder * doc/autoconf.texi (Shellology): Mention the problems with bash 2.05's use of ANSI quoting in its `set' builtin. 2001-10-22 Paul Eggert * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R): Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p, and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since POSIX decided to standardize on the int flavor of strerror_r. Always do char* test, as there's no reason not to. Assign to a char* var, to catch strerror_r that returns int*. * doc/autoconf.texi (Particular Functions): Document the above changes. Also, document the fact that AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R. * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P. 2001-10-20 Akim Demaille * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of the executable was missing from the log. 2001-10-20 Akim Demaille * lib/Autom4te/General.pm (&update_file): If destination is unchanged, remove the source. (&up_to_date_p): Don't be verbose, be debug. * bin/autoreconf.in: No longer support --m4dir. (&autoreconf): Display the full path of the configure.ac we are studying. Trace it only once.

Always run aclocal. * doc/autoconf.texi: Adjust. 2001-10-20 Akim Demaille * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX): Remove, dead. * bin/autoreconf.in (&autoreconf): Do not run gettextize when `intl' is already present, as it refuses unless --force. (&parse_args): Use -I, --include instead of the old Autoconf options. ($localdir, $autoconf_dir): Remove. (@include): New. (&maybe_autoreconf): New, to preserve $_ for File::Find. 2001-10-19 Jens Petersen * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk. * doc/autoconf.texi (Particular Programs): Likewise. 2001-10-19 Akim Demaille * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated file in @configure_input@.

From Russ Allbery. 2001-10-19 Ezra Peisach * bin/autoreconf.in (autoreconf): Display the path to the configure.ac being studied. 2001-10-18 Paul Eggert * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned long, to work around a bug in the HP C compiler version HP92453-01 B.11.11.23709.GP. * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works. (AS_BASENAME_EXPR): New macro. (AS_BASENAME_SED): Do not assume GNU sed semantics. (AS_BASENAME): Use 'basename' if that works; then try 'expr'; and fall back on 'sed' only if the other two fail. This makes AS_BASENAME act more like AS_DIRNAME.

(&handle_m4): Use it. * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the warnings are issued at each run. * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar is in the src tree. 2001-08-15 Akim Demaille * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required: don't waste time running `autoupdate --version' works. * tests/tools.at (autoupdating AC_PREREQ): Likewise. 2001-08-13 Akim Demaille * doc/autoconf.texi (ma): Rename this index as... (ac): this. 2001-08-13 Akim Demaille * Makefile.am: Remove dead code and dead comments. (pdf, html): New targets. * doc/autoconf.texi (Using Autotest): New chapter. * doc/Makefile.am (pdf): New targets. (CLEANFILES): Adjust. 2001-08-13 Akim Demaille * lib/autotest/general.m4 (AT_INIT): Log the start/stop dates and duration of the test suite. 2001-08-12 Alexandre Duret-Lutz * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load endianness for comparison instead of relying on AT_CHECK_ENV. 2001-08-11 Paul Eggert * doc/autoconf.texi, doc/install.texi: Add a copyright notice to the INSTALL file. 2001-08-11 Paul Eggert * NEWS: The autoconf manual now is distributed under the terms of the GNU Free Documentation License. * doc/autoconf.texi: Switch from old style copyright notice to FDL. Add an appendix "Copying This Manual" for the FDL. * doc/fdl.texi: New file, from . * doc/Makefile.am (autoconf_TEXINFOS): Add fdl.texi. 2001-08-10 Paul Eggert * AUTHORS, BUGS, ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, GNUmakefile, Makefile.maint, NEWS, README, README-alpha, TODO, configure.ac, lib/autoconf/Makefile.am, m4/atconfig.m4, m4/init.m4, m4/m4.m4, m4/missing.m4, m4/sanity.m4, tests/README, tests/aclocal.m4, tests/atspecific.m4, tests/base.at, tests/compile.at, tests/foreign.at, tests/m4sh.at, tests/m4sugar.at, tests/semantics.at, tests/suite.at, tests/tools.at, tests/torture.at: Add copyright notice. * tests/mktests.sh: Update year in copyright notice. 2001-08-12 Alexandre Duret-Lutz * tests/semantics.at (AC_C_BIGENDIAN): New test. 2001-08-11 Alexandre Duret-Lutz * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE, ACTION-IF-FALSE, and ACTION-IF-UNKNOWN. * doc/autoconf.texi (C Compiler Characteristics): Update documentation for AC_C_BIGENDIAN. 2001-08-11 Alexandre Duret-Lutz * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing magic values from an object file when cross-compiling. Based on code by Guido Draheim . 2001-08-10 Akim Demaille * bin/autom4te.in (&handle_output): Don't use `grep' with side effects. Suggested by Russ Allbery. 2001-08-10 Ralf Corsepius * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the current $prefix to the sub-configures. 2001-08-09 Tim Van Holder * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable extension (needed on BeOS). Reported by Guido van Rossum. 2001-08-09 Akim Demaille * bin/autom4te.in ($icache): Load it only if older than autom4te. 2001-08-07 Akim Demaille * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be removed. (at-setup-line): Huh? Be a variable `at_setup_line', not a file. No need to remove the files before and after the each test, before each test and at the end of the suite is enough. Display only the children `times', not the shell's. If the test failed or was skipped, at-times is not available. 2001-08-07 Akim Demaille Always produce testsuite.log, including when there are no failures. This helps getting information on skipped tests, and duration of the tests. Err, implement the latter btw. * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log. Dump information on the first run of each test. (AT_CLEANUP): Create `at-times' containing the duration of the test group. 2001-08-07 Akim Demaille The use of `dumpstat' revealed that `len' was used although it should not. m4_text_wrap was using it, but in the Autoconf world where it is legal. Hence (i) test M4sh in its own world, not Autoconf's, and (ii), ahem, fix the bug :) * lib/autotest/general.m4: Be sure the set good quotes, as tracing does not like `' instead of []. (AT_INIT): Forbid `^_?AT_'. And don't output such tokens. * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g', `script.as', and `autom4te.cache'. Remove `empty' and `macro' which are no longer used. * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New. * tests/m4sugar.at: Use it. * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'. 2001-08-07 Akim Demaille * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option. 2001-08-07 Alexandre Duret-Lutz * bin/autom4te.in (handle_output): Typo in quadrigraph substitution. 2001-08-04 Akim Demaille * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE) (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not AC_TRY_LINK. * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise. * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS) (AC_F77_MAIN): Likewise. 2001-08-04 Akim Demaille Don't rely on M4sugar outputting the patterns in files, since we might process the output _without_ running m4, hence without these files. * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'. * bin/autom4te.in (@Request::includes): Remove, unused. (@Request::source): Rename as... (@Request::input): this. (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'. (&handle_output): Fetch the patterns from the traces. `$forbidden' and `$allowed' are constant: use m//o. (&handle_m4): M4sugar no longer wants `m4_tmpdir'. (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only. 2001-08-04 Akim Demaille `autoconf && autoheader' is sped up. Now, speed up `autoheader && autoconf', i.e., in addition to caching traces, cache the output. * bin/autom4te.in (Request::cache): Rename as... (Request::id): this. ($cache, $icache, $tcache, $ocache): New. (&handle_m4): Save M4 output in the cache instead of $tmp. (&handle_output): Adjust. (&up_to_date_p): Check that the output cache is up to date too. (top level): Run `&handle_m4' iff force or the cache is invalid. Run `&handle_output' if the output cache is more recent. 2001-08-04 Akim Demaille * bin/autom4te.in ($force): New. (&parse_args, &print_usage): -f, --force is a new option. (&handle_output): CPP directives might have spaces after `#'. (&parse_args): The first file only can be frozen. 2001-08-04 Akim Demaille Don't let autom4te compute the `include' traces several times: first check that the trace cache file is up to date, and then compare its timestamp with that of the output. * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize the preamble. Don't require 5.005 as Autom4te::General does it, and better yet (use `use', not `require'!). * lib/Autom4te/Struct.pm: Rename the last occurrences of Class::Struct as Autom4te::Struct. * lib/Autom4te/General.pm (File::stat): Use it. (&mtime): New, export it. * bin/autom4te.in: Use it. Declare `$req' is invalid if it is outdated. Don't declare it valid before saving it if something went wrong. 2001-08-04 Akim Demaille Autom4te shall not encode Autoconf data, and preselecting traces must be proposed to the users. * bin/autom4te.in (@required_trace): Remove. (@preselect): New. (&parse_args, &print_usage): -p, --preselect is a new option. (&up_to_date_p): Adjust. * bin/autoconf.in: Preselect some Autoconf macros. 2001-08-04 Akim Demaille * tests/tools.at (autoconf --trace: user macros): Check traces on macros invoked without arguments, and macros invoked with multiple lines arguments. 2001-08-03 Alexandre Duret-Lutz * bin/autom4te.in (handle_traces): Fix rewriting of traces without arguments. 2001-08-03 Akim Demaille * bin/autoconf.in ($@): Work around the usual sh bug. From Nicolas Joly. 2001-08-03 Akim Demaille Clean up the handling of the M4 builtins tracing exception. * bin/autom4te.in (Request::request): Don't complete M4 builtins trace requests. (@m4_builtins): Rename as... (@m4_builtin): this. (%m4_builtin_alternate_name): New. (&parse_args): Complete the trace requests with alternate names. (&handle_traces): Hence no longer do it here. (&trace_requests): Remove, unused. 2001-08-03 Akim Demaille * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit, m4_if, and m4_wrap. 2001-08-03 Akim Demaille * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens. (m4_divert_pop): Dump the whole diversion stack when a diversion mismatch happens. * bin/autom4te.in (&handle_output): Remember of the first occurrence of a possibly undefined macro, not the last. Complain about the possibly undefined macros in the same order as the appear in the output. * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies. * tests/tools.at (autoconf: forbidden tokens, basic) (autoconf: forbidden tokens, exceptions): No longer sort autoconf's stderr, as it is now deterministic. Check that `dnl' is caught. 2001-08-01 Akim Demaille * configure.ac: Bump to 2.52c. 2001-08-01 Akim Demaille Version 2.52b. * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/. 2001-08-01 Akim Demaille Version 2.52a. 2001-08-01 Akim Demaille * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and `die'. (&END): New. * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your `END', as `Autom4te::General::END' will be triggered. * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy. * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of system to run `mv', `rm', and `cmp'. 2001-08-01 Akim Demaille * lib/Autom4te/General.pm (&unique): New. * bin/autoscan.in (&output): Use it to issue trace requests once. 2001-08-01 Akim Demaille * lib/Autom4te/General.pm: New. * bin/autom4te.in (Autom4te::General): Use it.
