autoconf/tests/tools.m4
Akim Demaille af8eb3314f Rewrite the autoheader chain on top of `autoconf --trace'.
* autoheader.m4: Dispatch the prototypes next to there AC_
siblings.
(AH_TEMPLATE, AH_VERBATIM): Move to...
* acgeneral.m4: here.
(AH_OUTPUT): New macro.
* autoheader.sh: Run `autoconf --trace' instead of `m4 autoheader.m4'.
* autoheader.m4: Remove.
* Makefile.am: Adjust.
* tests/tools.m4 (AH_DEFUN): Remove, no longer makes sense.
* tests/actests.m4 (autoheader::AC_TATOOINE): Remove, was used by
the test above.

# We use `/bin/sh -n script' to check that there are no syntax errors
# in the scripts. Although incredible, there are /bin/sh that go into
# endless loops with `-n', e.g., SunOS's:
#
# $ uname -a
# SunOS ondine 4.1.3 2 sun4m unknown
# $ cat endless.sh
# while false
# do
# :
# done
# exit 0
# $ time sh endless.sh
# sh endless.sh 0,02s user 0,03s system 78% cpu 0,064 total
# $ time sh -nx endless.sh
# ^Csh -nx endless.sh 3,67s user 0,03s system 63% cpu 5,868 total
#
# So before using `/bin/sh -n' to check our scripts, we first check
# that `/bin/sh -n' is not broken to death.
