* acgeneral.m4 (AU_DEFINE): New macros, pulled out from AU_DEFUN.
Defines a macro in `autoupdate::' with all the required wrapping
for `autoupdate'.
(AU_DEFUN): Use it.
(AC_OUTPUT): When dispatching your arguments, use ifval, not
ifset!
Dispath actions to AC_CONFIG_COMMANDS not AC_OUTPUT_COMMANDS, to
avoid unneeded warnings for obsolete use of AC_OUTPUT_COMMANDS.
(autoupdate::AC_OUTPUT): New macro.
* doc/autoconf.texi (Writing configure.in, the example): Don't
advocate AC_OUTPUT with args.
(Output, AC_OUTPUT with args): Simplify the documentation, and
provide the translation into the new scheme.
Propagate what remained into the proper sections.
* acgeneral.m4 (AC_OUTPUT_COMMANDS): AU_DEFUNed in terms of
AC_CONFIG_COMMANDS.
(AC_OUTPUT_COMMANDS_CNT): New variable, declared both in
`autoconf::' and `autoupdate::'.
(AC_OUTPUT): Register your arguments to AC_OUTPUT_COMMANDS only if
there are to avoid spurious `run autoupdate' messages.
* doc/autoconf.texi (Libraries): Document the changes.
are none.
* acgeneral.m4 (AC_OUTPUT): Don't register $1 to `AC_CONFIG_FILES'
if $1 is empty.
Normalize the names of the sections in `config.status --help'.
* acgeneral.m4 (_AC_CONFIG_COMMANDS_INIT): New macro which will
collect the `INIT-CMDS'.
(AC_CONFIG_COMMANDS, AC_CONFIG_LINKS, AC_CONFIG_HEADERS,
AC_CONFIG_FILES): Use it, and also temporarily divert to -1
instead of spamming dnl everywhere.
(AC_OUTPUT_CONFIG_STATUS): Make sure to output the INIT-CMDS
before the other sections, it'd be a pity to initialize after the
use :).
* doc/autoconf.texi (Configuration Actions): New section,
documenting the common behavior of AC_CONFIG_FILES,
AC_CONFIG_HEADERS, macro AC_CONFIG_COMMANDS, and AC_CONFIG_LINKS.
(Configuration Files): Document $2 and $3 of AC_CONFIG_FILES.
(Configuration Headers): Document $2 and $3 of AC_CONFIG_HEADERS.
(Configuration Commands): Document $2 and $3 of AC_CONFIG_COMMANDS.
(Configuration Links): Document $2 and $3 of AC_CONFIG_FILES.

(_AC_VERSION_UNLETTER): this. All callers changed.
Implement the scheme proposed by Alexandre Oliva:
Nl -> (N+1).-1.(l#)
(_AC_VERSION_COMPARE): New macro.
(AC_PREREQ): Use it.
yourself, in order to give better error messages.
(AC_CONFIG_IF_MEMBER): Adapted to the above change.
Quote some regexp active characters ([+.*]).
Suggested by Alexandre Oliva.
* doc/autoconf.texi (Common Behavior): New section, to document
the common behavior of the macros.
(Standard Symbols): New subsection. Describes the transformation
of the AC_DEFINEd names.
(Default Includes): New subsection. Obvious content.
All the ``callers'' updated.
while loops which are breaking conftest.defines and
conftest.undefs into smaller snippets: just use the proper
condition for the while.
Suggested by Alexandre Oliva.
* doc/autoconf.texi (Concept Index): New section.
Various entries added.
(Typedefs): Renamed as...
(Types): this. Pay attention to not limiting the documentation to
the typedefs.
(Particular Types): Mention the equivalent generic test.
Promote the GNU coding style at various places.
given in the prologue of acobsolete.m4.

Disable the name spaces `autoconf', and `libm4'. Disable libm4.

Can run on several files at once (for instance m4/*.m4).
Don't touch files that are up to date.
Run m4 on autoupdate.m4f instead of playing with sed.
Use AU_DEFUN.
* acgeneral.m4 (AC_LINK_FILES, AC_ENABLE, AC_WITH): Use AU_DEFUN,
remove the call to AC_OBSOLETE.
* acspecific.m4 (AC_CYGWIN32): Likewise.
* acoldnames.m4: Replaced all the definitions via `define' or
`AC_DEFUN' to use `AU_DEFUN'.
* acoldnames.m4: Use `#', not `dnl'.

More temporary files that one can browse when debugging.
Don't ${var}, just $var.
Don't dump --help when the arguments are invalid.
(config_h): Use the empty value instead of `undefined' to check
that it is defined.
* acspecific.m4: Formatting changes.
yourself. This allows to see everything that is AC_PROVIDEd via
autoconf --trace.
(AC_SPECIALIZE): define'd, not AC_DEFUN'd.
(AC_PROVIDE): Use define with a single arg, instead of an empty $2.
* 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.
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.

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.

acgeneral.m4.
