Fix the bugs discovered.
* acgeneral.m4 (AC_CANONICAL_THING): Quote the
AC_REQUIRE([AC_CANONICAL_HOST]). Bug triggered by the use of
AC_CANONICAL_BUILD alone in configure.in. Also, quote the
arguments of macros (eg, ifelse([$1]...), not ifelse($1...)).
(m4_case): New macro.
(AC_LINKER_OPTION): Don't clash with user's name space
(s/i/ac_link_opt).
(AC_LIST_MEMBER_OF). You mean AC_FATAL, not AC_MSG_ERROR.
Quote properly the argument.
dnl out the empty lines that result from m4 pure code.
Don't pollute the user name space.
Use AC_SHELL_IFELSE.
(AC_F77_NAME_MANGLING): Don't use `test -o'. There are still
name space problems.
* tests/Makefile.am (macros.m4): Also fetch the macros from
acgeneral.m4.
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.
