from /tmp.
Thanks to Bill Moseley and Paul Eggert.
* lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
the tmpdir must be created.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
dir be in the build tree, instead of $TMPDIR.
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.
* config/auxdir.m4, config/cond.m4, config/depend.m4,
* config/init.m4, config/install-sh.m4, config/lispdir.m4,
* config/missing.m4, config/sanity.m4, config/select.m4,
* config/strip.m4: Remove, to ease sync'ing with any version of
Automake.
trailing files, don't apply `-rf' to files which might not be
created by configure (core, core.*, and *.core), but just `rm -f'.
Suggested by Jonathan Kamens.
Remove, replaced by...
* tests/wrappl.in: Be common for all the Perl executables.
In particular autoscan and autoheader want -I.
* configure.ac: Adjust.
* lib/autoscan/headers: errno.h is portable.
