* acgeneral.m4 (AC_TRY_COMPILER, AC_TRY_LINK_FUNC, AC_CHECK_LIB,
AC_TRY_COMPILE, AC_TRY_LINK, AC_TRY_RUN_NATIVE, AC_CHECK_FUNC):
Use AC_LANG_CASE instead of ifelse (AC_LANG, ...).
(AC_TRY_LINK_FUNC): Quote the body the the AC_DEFUN (whoa, how
could this survive so long?!?).
* doc/autoconf.texi (Header Templates): Promote #if over #ifdef;
and #undef over #define in templates.
* acspecific.m4 (AC_DECL_SYS_SIGLIST, AC_FUNC_MMAP,
AC_FUNC_SETPGRP, AC_FUNC_VFORK, AC_FUNC_SELECT_ARGTYPES): Use #if,
not #ifdef and #ifndef, indent CPP directives.
default headers in the INIT section of configure: the reason is
that AC_INCLUDES_DEFAULT is called unquoted, and this results in
an un expected behavior. Thanks to Roman V. Shaposhnick for the
details.
The current implementation is not satisfying: the default headers
are defined in the INIT section even if they are not used.
* acgeneral.m4 (Prologue of AC_INCLUDES_DEFAULTS): Dump the
definition of ac_includes_default in the INIT section of
configure.
(AC_INCLUDES_DEFAULTS): Use it.
test.
* acgeneral.m4 (AC_CHECK_SIZEOF): Don't over quote $1, some []
were left in the C code, and had the macro fail.
Use AC_INCLUDES_DEFAULT.
* doc/autoconf.texi: Mention default includes. Explain stdio.h
must always be given.
* tests/atspecific.m4 (TEST_MACRO): Updated the list of
exceptions.
(AT_CHECK_DEFINES): New macro, to check the content of config.h.
* tests/semantics.m4: All the tests are updated to use
AT_CHECK_DEFINES.
Test AC_CHECK_SIZEOF, AC_CHECK_HEADERS, and AC_CHECK_FUNCS.
Autoconf testing.
* tests/suite.m4 (AT_TEST_MACRO): Moved to
* tests/atspecific.m4 (AT_TEST_MACRO): here.
* tests/syntax.m4 (TEST_MACRO): Moved to
* tests/atspecific.m4 (TEST_MACRO): here. Don't test /^AC_INIT/,
nor /^AC_PROG_(CC|CXX|F77)_(GNU|WORKS)$/: they are already
tried elsewhere.
* tests/Makefile.am: Adjusted.
condition out the test case if __cpluscplus.
Don't document the autoheader template twice, one is enough.
* autoheader.m4 (AC_CONFIG_HEADER): don't hook on this guy, but
on...
(AC_CONFIG_HEADERS), since the former is defined on the latter.
for it. Just quote properly!
condition out the test case if __cpluscplus.
AC_REQUIRE AC_PROG_CC_STDC.
Fix slightly the display of the result (formerly the first run
says `none needed', and later, because of the cache `no').
(AC_C_INLINE, AC_C_VOLATILE): AC_REQUIRE AC_PROG_CC_STDC.
* doc/autoconf.texi (AC_C_CONST): Give a few hints on the
motivation for trusting the C++ compilers.
(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.
* acgeneral.m4 (AC_CANONICAL_THING): define, not AC_DEFUN.
Don't AC_PROVIDE, there is no need.
When calling `config.sub`, also || exit 1, to catch failures from
config.sub.
* acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Use ac_val, not val.
(AC_EXEEXT): Use ac_file, not file.
* tests/actest.m4: New file, holding extra Autoconf macros used
during the testing.
(AC_ENV_SAVE): New macro, save the sh variables in a file.
* tests/suite.m4 (AT_TEST_MACRO, Generation of configure.in):
include actest.m4, and call twice AC_ENV_SAVE to compare the
variables before and after the macro.
* tests/Makefile.am (macro.m4): Don't test macros that are
required: they will be tested somewhere else.
* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and
AC_Member_Member which were complicating more than simplifying.
(AC_CHECK_DECLS): Use m4 lists.
(AC_CHECK_TYPES): A comma was missing.
* autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
* doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
lists.
* tests/semantics.m4: New file. Collection of semantical tests:
verify that the tests are positive and negative when appropriate.
Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
* autoheader.m4 (AH_DEFUN): New macro. Combination of define and
AH_HOOK.
(AC_TRY_RUN, AC_DEFINE, AC_DEFINE_UNQUOTED, AC_CHECK_LIB,
AC_CHECK_HEADERS, AC_CHECK_HEADERS_DIRENT, AC_CHECK_DECLS,
AC_CHECK_FUNCS, AC_CHECK_SIZEOF, AC_PROG_LEX, AC_CHECK_MEMBERS,
AC_CHECK_TYPE, AC_FUNC_ALLOCA, AC_CHECK_TYPES, AC_C_CHAR_UNSIGNED,
AC_AIX, AC_F77_WRAPPERS, AC_CONFIG_HEADER): All the former calls
to define and AH_HOOK in autoheader.m4 are replaced by AH_DEFUN.
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).
extern software (so that the test suite doesn't fail on them).
* acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
optional $2: exit status.
* doc/autoconf.texi: Document.
* acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.
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.
A test suite will be introduced which tries to run all the
specific macros, but hasbeen'd macro make configure die with bad
exit status. So we wish to distinguish live macros from defunct
macros at the moment they are AC_DEFUN'd, not in their body. Hm,
defunct, defunct... Hey! That's a good name!
* acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
but for macros which are no longer defined. Replaces AC_HASBEEN.
(AC_HASBEEN): Defunct. Well, removed in fact.
(AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
AC_DEFUNCT.
* acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
(AC_XENIX_DIR): It was defunct even before I declared it was: was
depending upon AC_DIR_HEADER which is defunct. So AC_DEFUNCT'ed
now.
(AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
too are defunct now.
* autoconf.texi (Obsolete Macros): Replace the documentation of
AC_HASBEEN with that of AC_DEFUNCT.
