workaround for ${1+"$@"}.
* doc/autoconf.texi (Shell Substitutions): Explain it.
From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
* lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to
AS_SHELL_SANITIZE.
Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.
($(TESTSUITE)): Use $(autotest_m4f_dependencies).
(wrapsh.in): New target.
* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.
* bin/autoupdate.in: Ditto.
* bin/autoheader.in: Reworded a few comments.
* bin/autoconf.in: Reworded help text for a few options.
* bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
* bin/autoscan.in, bin/autoupdate.in: Ditto.
Map --localdir, --autoconf-dir onto it.
Forward autom4te's options instead of interpreting them.
* bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
There is no such envvar since the inception of autom4te.cfg.
* bin/autom4te.in (&parse_args): Uniquify `@include'.
* bin/autoupdate.in: Adjust, and perform more control.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
* tests/autoconf: Dittowise.
* bin/autom4te.in (&find_file): Support `FILE?' standing for
optionally `FILE'.
Use -e, not -f, since /dev/null for instance is OK.
(&parse_args): Adjust.
* lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
* bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
* bin/autoscan.in, autoupdate.in: Use exclusively the name of the
installed peer executables, only PATH is allowed to resolve it.
Pass `autoconf_dir' via options, not via invisible envvars.
* lib/Autom4te/General.pm (&find_peer): Remove.
* lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
`abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
* man/Makefile.am: Let help2man rely on PATH instead of trying to
find the executables for it.
* tests/Makefile.am: Major cleanup. Too lazy to document...
* tests/atlocal.in: Remove all the obscure envvar manipulations.
We only need PERL.
* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing
--autoconf-dir and others is related to running non installed
Autoconf executables. So don't do that, leave it to...
* tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
* tests/autoscan: New.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
refer to library files: rely on --language.
* lib/Makefile.am (edit, autom4te.cfg): New.
* bin/autom4te.in (BEGIN): Simplify.
Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
(&load_configuration): New. Use it.
(&parse_args): Support --mode, --set, and --melt.
* bin/autoconf.in: Simplify and adjust.
* tests/Makefile.am (AUTOMAKE): Use --set.
* tests/atlocal.in: Adjust.
* BUGS: distcheck and check are weak.
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.
* test/tools.at: Use AT_CHECK_AUTOCONF.
(AWK portability): Remove, for autoconf no longer uses AWK.
(Syntax of the Perl scripts): New.
* configure.ac: autoconf no longer needs an AWK with a good
regexp engine.
Use a static test on AC_PACKAGE_VERSION.
* autom4te.in (&up_to_date_p): Output depends on the arguments.
* lib/autoconf/Makefile.am: Ship version.m4, maintainer file.
* tests/atconfig.in (PERL): New.
* autoconf.in ($task, task trace): Remove, merely pass --trace to
autom4te.
* autoheader.in: Don't pass `-' to autoconf, rather, a tmp file.
(Because I found no way for autom4te to accept `-').
* autom4te.in (&Request::request): Beware of M4 builtins.
(END): Don't try to remove the content of an empty dir.
(&parse_args): Default is `$f:$l:$n:$%', not `$f:$l:$n:$*'.
(&handle_output): Set a default value to `$forbidden'.
* autoupdate.in (&verbose, &xsystem): New, from autom4te.in.
($autoconf): Pass --debug and --verbose.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Clean up autom4te's
cache.
* autoconf.in ($automate): New var.
(task script): Use autom4te.
* autom4te.in (File::Spec): Use it.
(&find_file): New.
(&parse_args): --warning is -W, not -w.
Find the top level files.
(&handle_m4): Pass the warnings flags.
Don't report verbosely m4's failures, unless requested.
(&handle_output): Don't complain for forbidden tokens in comments.
Be sure to report all the forbidden tokens within a single line.
(&trace_format_to_m4): Preserve `$_'.
(&handle_traces): Sort the output macros.
(&up_to_date_p): Find the files before trying to get its time stamp.
