* 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.
autoheader are Perl programs.
(autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
(autom4te): Specify that the sources are in the $srcdir.
* doc/autoconf.texi (Installation Directory Variables): Adjust.
* doc/autoconf.texi (Installation Directory Variables): Update.
(Limitations of Make): Some about `Single Suffix Rules and
Separated Dependencies'.
* bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
(ifnames, autoscan, autom4te): Un-factor into several rules.
make handles suffix-rules differently from GNU make.
(SUFFIXES, .in): Remove.
(autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
Move the body of the old .in rule here.
(ifnames, autoscan, autom4te): Since we don't only depend on
configure.ac variables (such as VERSION etc.), but also on prefix
and so forth, depend on Makefile, not configure.ac.
Reported by Alexandre Duret-Lutz.
* doc/autoconf.texi (Installation Directory Variables): Adjust.
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.
Pass $at_debug_args to the rerun test suite.
* lib/m4sugar/Makefile.am (DISTCLEANFILES): New.
* bin/Makefile.am (ETAGS_SH): Don't use characters ranges.
From Paul Eggert.
* 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.
