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.
* lib/autoconf/autoconf.m4: Include it.
* lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
that were listed in the original autoscan.list.
* lib/autoconf/headers.m4: Similarly with headers.
* lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
(.m4.m4f): Don't pass --prepend-include, since that's done by
tests/autom4te itself.
* lib/autoscan/Makefile.am: Include freeze.mk.
(autoscan.list): New target --this file is no longer a source.
(autoscan.pre): New file.
Adjust all uses.
(&init_tables): When --debug, report the list of rules to ease
tracking changes in autoscan.list.
* lib/autoscan/autoscan.list (function): Strip comments, sort.
* lib/autoscan/identifiers, lib/autoscan/makevars,
* lib/autoscan/programs: Make the `kind' explicit, i.e., each
`functions' line is now prefixed with `function:'.
* bin/autoscan.in (&init_tables): Adjust.
word: there is no `default' macro for autoscan.
* bin/autoscan.in (&init_tables): Reject entries with no macro at
all.
* lib/autoscan/functions, lib/autoscan/headers: Make the macro
explicit.
* 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.
(&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
hand, which is not portable.
(&error): New.
* bin/autom4te.in: Use them.
Use &error instead of die.
* tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
Adjust.
* bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
options and use $AUTOM4TE_PATH.
* doc/autoconf.texi: Remove documentation of autom4te
--include-envvar and --site-macro-subdir options and document
use of $AUTOM4TE_PATH.
* lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
arguments from each language section.
bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
so that Emacs setups GNU style for perl-mode and cperl-mode.
name, so that symlinks to 'autoconf' work properly. Bug reported
by Bruno Haible.
* bin/autoheader.in (AUTOM4TE): Likewise.
* bin/autoreconf.in (autoconf, autoheader): Likewise.
* bin/autoscan.in (autom4te): Likewise.
* bin/autoupdate.in (autom4te): Likewise.
files to be 1 second older; just set them to be the same time.
Also, sleep 1 second after the first aclocal, to work around
problems with sub-second time stamps on the input files.
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.
