output, so that we can track spurious m4sugar output.
* tests/local.at: Require 2.57.
(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.
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.
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.
to a shell that can handle redirection or quoting correctly.
Override SHELL with the shell detected by configure.
Use of $^O suggested by Tim van Holder.

* bin/autoscan.in (BEGIN): Likewise.
* bin/autoupdate.in (BEGIN): Likewise.
* bin/ifnames.in (BEGIN): Likewise.
* bin/ifnames.in: Add final newline to help and version messages.
* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
to cope with DOS-style absolute paths, when constructing
${ac_make}.
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
When constructing paths with IFS=:, quote the path. If we're
constructing a DOS-style absolute path, we don't want to split it
on the colon.
* tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
in description.
are a few warnings.
* lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
Quote for Perl '' strings, not "".
* bin/autoheader.in: Invoke autoconf to get '' strings, not ""
strings.
characters is a syntax warning now.
(_AS_QUOTE): Accept $2 as list of characters to quote.
* lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
Quote for Perl, not sh.
* bin/autoheader.in: When $debug, report the file which is
`do'ne.
* tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
`@', to tickle Perl's lists.
Reported by Carlos Velasco.
Fixes the `AC_ARG_VAR' test failures.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
* lib/freeze.mk (check-forbidden-patterns): New.
* lib/autoconf/Makefile.am, lib/autotest/Makefile.am
* lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
* doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
/dev/null.
Reported months ago by H. Merijn Brand.
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.
* 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.
(AT_CHECK_AUTOUPDATE): Likewise.
* tests/tools.at (autoupdate): Adjust.
* tests/semantics.at (AC_C_BIGENDIAN): Likewise.
