Fix a bit of the brokenness of AC_CHECK_TYPE.
* acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
the former AC_CHECK_TYPE. This macro is exactly the one that
ought to be named AC_CHECK_TYPE: it just checks, and executes user
actions. In the future, this macro ought to be renamed
AC_CHECK_TYPE.
There is a big difference with the former AC_CHECK_TYPE: instead
of grepping in the headers, it tries to compile a variable
declaration. This is both safer, slower, and better, since now we
can check for compiler types (e.g., unsigned long long).
(AC_CHECK_TYPES): The looping and AC_DEFINEing version of the
previous macro. Uses m4 loops.
(AC_CHECK_TYPE): Reimplemented on top of AC_CHECK_TYPE_INTERNAL.
* autoheader.m4 (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros,
hooked.
* autoconf.texi (@ovar): New macro, for optional variables.
(Generic Typedefs): Document AC_CHECK_TYPES.
* autoheader.texi: (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros.
(Epilogue): Hooks them.
Rename the family AC_NEED_DECL as AC_CHECK: it is more uniform,
but keep defining NEED_FOO_DECL when `foo' is not declared. Files
not using Autoconf behave better when declarations lacks than when
they are wrong. So the unset position should off, hence #if NEEDS
instead of #if !HAVE (which is triggered when HAVE is not set).
* acgeneral.m4 (AC_NEED_DECL): Renamed as...
(AC_CHECK_DECL): This. Make sure the arguments are the usual
IF-FOUND, IF-NOT-FOUND.
(AC_NEED_DECLS, AC_CHECK_DECLS): Likewise.
* autoconf.texi (Generic Declarations): Document the changes
aforementioned.
* autoheader.m4 (AH_NEED_DECLS): Renamed as
(AH_CHECK_DECLS): This.
(AH_HOOKS): Hook AH_CHECK_DECLS on AC_CHECK_DECLS instead of
_NEED_.
New macro: AC_CONFIG_FILES which is very much like AC_OUTPUT but
that one associates commands to run when a config file is
created. For instance for a shell script `foo', one uses
AC_CONFIG_FILES(foo, chmod +x foo).
In addition, check that the same name is never used twice in
config files, headers, subdirs and links.
* acgeneral.m4 (m4_append): Don't insert new line between
elements.
(m4_list_append): New macro.
(AC_CONFIG_IF_MEMBER): New macro which tests if a file is member
of a config list.
(AC_CONFIG_UNIQUE): New macro which ensures that a config file
name is not yet used.
(AC_CONFIG_HEADER, AC_CONFIG_LINKS, AC_CONFIG_SUBDIRS): Use
AC_CONFIG_UNIQUE.
* acgeneral.m4 (AC_CONFIG_FILES): New macro.
(AC_LIST_FILES): New list, which stores arguments of
AC_CONFIG_LISTS the same as AC_LIST_LINKS stores AC_CONFIG_LINKS
etc.
(AC_OUTPUT): No longer rely on $1 to designate the config files:
register them via AC_CONFIG_FILES. All uses of $1 replaced by
uses of AC_LIST_FILES.
(AC_OUTPUT_FILES): Run the commands associated to the
CONFIG_FILES.
* configure: Regenerate.
* aclocal.m4: New generated file.
* Makefile.in: Regenerate with Automake.
* testsuite/Makefile.in: Likewise.
1999-10-31 Akim Demaille <akim@epita.fr>

* acgeneral.m4: No longer define AC_ACVERSION, include
acversion.m4.
* acversion.m4.in: New AC_CONFIG_FILE.
* acspecific.m4: Few formating changes.
* autoconf.texi: No longer define EDITION, VERSION and UPDATED:
include version.texi.
AC_OUTPUT the Makefiles mentioned below and acversion.m4.
* configure.in: Use AM_INIT_AUTOMAKE.
Do not AC_ARG_PROGRAM: AM_INIT_AUTOMAKE does it.
* Makefile.am: New file.
* mdate-sh: Likewise.
* missing: Likewise.
* testsuite/Makefile.am: Likewise.
1999-10-05 Akim Demaille <akim@epita.fr>

1999-10-01 Akim Demaille <akim@epita.fr>
Make the handling of the configuration links (AC_LINK_FILES)
exactly the same as that of configurations files (AC_OUTPUT_FILES)
and headers (AC_CONFIG_HEADERS). As a result, it is sane to run
./config.status src/libmy_lib
or
CONFIG_LINKS=src/lib_mylib:lib/lib_mylib ./config.status
* acgeneral.m4 (AC_LINK_FILES): Use AC_FATAL to diagnose bad
number of argument.

accurately determine and is not essential. Fix for autoconf/7.
