and improve the sed-related documentation a bit.
* doc/autoconf.texi (Installation Directory Variables): Use
our own style advice re 's,a,b,' versus 's|a|b|'. Use "Sed"
rather than "sed" when talking about Sed in general.
(Particular Programs): Likewise.
(Coding Style): y is like s with respect to / and ,.
(Limitations of Usual Tools): Document the weird restrictions
that Posix has about { }. Use better quoting.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
Rewrite to conform to Posix rules about { } in sed scripts.
* lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
* tests/foreign.at (Libtool): Likewise.
* tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
Use our own style advice re 's,a,b,' versus 's|a|b|'.
* tests/suite.at: Use it.
* tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
* tests/autotest.at (Keywords): Test keywords combinations.
The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
and CONFIG_COMMANDS are not processed in four separate loops.
Instead, there is one main loop. This alows that the common code
is expanded only once, thus config.status (and configure) is smaller.
The registration mechnism in AC_CONFIG_FILES and cousins also changed;
the AC_LIST_FILES and cousins macros are no longer used.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
(_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
_AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
contains the initialization, nor the for loop, nor the associated
commands; all these go to ...
(_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
_AC_OUTPUT_CONFIG_STATUS.
(_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
(_AC_OUTPUT_FILE): The creation of the sed script ...
(AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
(_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
_AC_OUTPUT_MAIN_LOOP.
(_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
_AC_CONFIG_COMMANDS): Use ...
(_AC_CONFIG_FOOS): ... this new macro, which uses these ...
(_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
(_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
_AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
(_AC_CONFIG_DEPENDENCY): Update, it uses these ...
(_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
... new macros.
(_AC_CONFIG_UNIQUE): Update.
(AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
Replaced by this ...
(_AC_LIST_TAGS): ... new common macro.
(AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
AC_LIST_COMMAND_COMMANDS): Replaced by this ...
(_AC_LIST_TAG_COMMANDS): ... new common macro.
(_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
this didn't belong to the `config commands' section.
(_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
(AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
to the `config commands' section either.
(AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
(_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
... and many changes to the comments nearby.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
set ac_subdirs_all='_AC_LIST_SUBDIRS'.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
(#define header templates): The comment at the top of the generated
header now includes the name(s) of the source file(s).
Several unrelated small changes:
* lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
parameter to AC_DIAGNOSE.
* lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
(_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
(AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
with AU::AC_OUTPUT.
(AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
in AC_OUTPUT doesn't double-quote it either.
* tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
parameters.
(AS_VERSION_COMPARE): New macro. The API is taken from CVS,
but the implementation is entirely different and is designed
to be compatible with glibc strverscmp.
* tests/m4sh.at (AS_VERSION_COMPARE): New test.
now contain newlines, and substituted files must be referenced on
a line alone; the sed scripts to substitute them are now very
different.
(_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
commands can be put in a sed script portably.
* doc/autoconf.texi (Setting Output Variables): Document above
changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
use of multiline substitution.
* tests/torture.at: No longer expect substitution of newline to fail.
* 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.
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.

unportable file names.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
(AC_INIT): Use it.
(_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
ac_pwd, and quote srcdir.
* lib/autotest/general.m4 (AT_INIT): Quote file name args.
/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 "</dev/null" since it's now done at the top of
'configure'.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
* lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
* doc/autoconf.texi (File Descriptor Macros): New section.
(Printing Messages): Mention it.
* tests/base.at (Input/Output): 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.
(AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
(AC_SAVE_STATE): Move environment grep...
(AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
(AT_CONFIG_CMP): New macro.
(AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
* tests/c.at (Extensions): Do not exit early.
* tests/atlocal.in: Inherit $GREP.

excess test name quoting.
* tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
CPPFLAGS to `configure' instead of setting it in `configure'.
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.
(m4_require): Don't put the ``is required by'' line to the
execution stack; slightly improve the out-of-a-defun error message.
(_m4_divert_grow): New macro, counter for the temporary diversions.
(_m4_require_call): Use it.
* tests/m4sugar.at (m4_require): Expect output without the
``is required by'' messages.
signals that the package uses Automake; a `Makefile.am' is typical but
not essential. Reported by Magnus Therning.
* tests/torture.at (autoreconf.): New banner.
(autoreconf and non-AC configure): Rename to `Non-Autoconf
AC_CONFIG_SUBDIRS'.
(autoreconf an empty directory): Rename to `Empty directory'.
(Unusual Automake input files): New test.
