(Specifying Names, Canonicalizing): Remove all references to the
backward compatibility hooks. Rather, collect them all into...
(Hosts and Cross-Compilation): this new section.
* doc/install.texi (System Type): Ditto.
* lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
that `--host' implies cross-compilation.
AC_PREFIX_PROGRAM fails with dashed program names
* lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
variable when looking for the prefix program.
Now it also works for shell variables.
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.
(&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.
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.
Be sure to honor --force with gettextize.
Always run aclocal.
* doc/autoconf.texi: Adjust.
generates too many bug reports.
* lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
status when executing the ACTION-IF-FALSE.
* tests/base.at (AC_TRY_*): Rename as...
(AC_TRY_COMMAND): this.
(AC_RUN_IFELSE): New.
* tests/compile.at (Extensions, C keywords)
(AC_PROG_CPP requires AC_PROG_CC, GNU Fortran 77)
(Broken/missing compilers, AC_PROG_CPP with warnings)
(AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
* tests/c.at (Extensions, C keywords)
(Broken/missing compilers, AC_PROG_CPP with warnings)
(AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
(AC_PROG_CPP requires AC_PROG_CC): here and...
* tests/fortran.at (GNU Fortran 77): there.
* doc/autoconf.texi (autoconf Invocation): Fix the example:
AC_TRY_RUN is about compilation, not shell commands.
(Test Programs): AC_TRY_RUN works as used to be advertised.
ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
(_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
builddir, buildpath, top_builddir, and top_buildpath.
(_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
the current directory.
* lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
variables *before* changing the current directory.
Skip nonexistent dirs.
* doc/autoconf.texi (Preset Output Variables): Document these
variables.
* lib/autotest/general.m4: Do not reset AT_victims.
Don't compute at_srcdir nor at_top_srcdir.
* tests/tools.at: Hence use top_srcdir.
* tests/Makefile.am, tests/autoconf, tests/autoheader,
* tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
Remove.
* tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
* tests/wrapsh.in, tests/autoupdate.in: New.
* tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
* configure.ac: Build the position independent wrappers.
* man/Makefile.am: Now that test wrappers are position
independent, use them and drop dark envvar magic.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
`$LINENO' support replacement when not supported.
(_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
them explicitly to be sure they are not output before this section
(via m4_require). Cosmetic only.
* lib/autoconf/c.m4, lib/autoconf/general.m4,
* lib/autoconf/programs.m4: Replace all the occurrences of
`__oline__' with `$LINENO'.
* doc/autoconf.texi (Special Shell Variables): Document LINENO.
* bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
New, extracted from main.
Use IO::File wherever possible.
(input.m4): Be constant, use -I instead of hard coding $tmp.
Therefore be a quoted heredoc.
Don't invoke `_au_disable', since ac was not loaded, but just
`unm4.m4'.
* bin/autoupdate.in: Use --include, -I, and --force, -f, too.
Use directly autom4te, not autoconf.
* tests/autoupdate: $top_srcdir/lib is needed too for melt files.
`ac_top_builddir' to mimic Automake's vocabulary, which much more
readable.
Adjust callers.
* doc/autoconf.texi (Configuration Actions): Document the vars
available in commands.
Emphasize the risks of collisions in init-cmds.
