(AT_CASE): new macro.
(AT_CHECK): Use it. Don't changequote for patsubst, there is no
need.
* tests/syntax.m4 (TEST_MACRO): Don't run AC_ARG_VAR.
Reported by Jim Meyering.
Use AT_CASE.
Fix the discovered bugs.
* tests/atgeneral.m4 (AT_CHECK): Don't just exit 1 when you want
to propagate the failure of a test: exit with the same exit
status, at least to preserve 77 (=ignore).
* tests/syntax.m4 (TEST_MACRO): Run also autoheader. Don't run
this test on all the macros, some just cannot run without
arguments.
* acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): In the if egrep/fi for
#define templates, add a `:' to prevent syntax errors in
config.status when there are no AC_DEFINE performed.
* autoheader.m4 (AH_TEMPLATE): Don't use _AC_SH_QUOTE here, use it
in...
(AH_VERBATIM): here. Now AH_C_UNSIGNED_CHAR is no longer failing
(formerly it would produce a non backslashed backquote, which
made sh choke).
Introduce a new style of testing, independent from DejaGNU.
Introduce the logistics.
* configure.in: Initialize AT, and output tests/atconfig, and
tests/Makefile.
* m4/atconfig.m4: New file.
* m4/Makefile.am: Adjusted.
* aclocal.m4: Include atconfig.m4.
* Makefile.am: Adjusted.
* tests/Makefile.am: New file.
* tests/atgeneral.m4: Likewise.
* tests/atconfig.in: Likewise.
Write tests.
* tests/syntax.m4: New file, in charge of checking the validity of
the sh code produced by the macros defined in acspecific.m4.
acgeneral.m4 is not checked here, because these macros require
arguments.
* tests/suite.m4: New file. Run syntax.m4.
