directory for AC_CONFIG_COMMANDS' first argument exists.
This makes valid the invocation of _AC_SRCPATH that follows.

* doc/autoconf.texi (Configuration Commands): Adjust.
* 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.
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/autom4te.in (BEGIN): Likewise.
* bin/autoreconf.in (BEGIN): Likewise.
* 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.
