Be sure to read this file if you're using a non released Autoconf.
* tests/tools.at (Syntax of the scripts): The non built tools are
in `$top_srcdir', not `..'.
(autoconf --trace): When using `-i' we need the src tree, not the
build tree.
* m4sugar.m4 (_m4_require): $2 defaults to $1.
Rename as...
(m4_require): this.
* acgeneral.m4 (_AC_REQUIRE): Remove, use m4_require if you want
to get into the gory details.
The main difference is that the former requires AC_LANG_COMPILER.
* aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
(AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
macros. Issue a warning when looking for the Fortran 77
preprocessor instead of an error.
(AC_LANG_COMPILER): Check that it is run before the corresponding
AC_LANG_PREPROC.
(AC_PROG_C
(AC_LANG_COMPILER_REQUIRE): Don't call directly
AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
the generic code in AC_LANG_COMPILER is run.
(AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
(AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.
Propagate AC_LANG_PREPROC_REQUIRE.
* acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
AC_REQUIRE_CPP.
* acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
AC_REQUIRE_CPP, inner macro will do it.
* aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
(AC_C_PROTOTYPES): Likewise.
(AC_C_STRINGIZE): Yeeks! The body of AC_CACHE_CHECK was not
quoted. Use @%:@ do assist Emacs.
For some reason (don't ask), this revamping revealed that
AC_PROG_CC_STDC, because of the `break', does not clean its tmp
files.
* aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
out of AC_COMPILE_IFELSE.
Be sure to clean the tmp files.
instead of hard coded `configure'.
* acgeneral.m4 (AC_COPYRIGHT): s/configure.in/__file__/.
(_AC_INIT_DEFAULTS_FDS): Append to AC_FD_LOG instead of creating
it. No longer insert the configure banner.
(_AC_INIT_DEFAULTS): Create config.log with the banner.
Define `as_me'.
(_AC_INIT_PARSE_ARGS, _AC_INIT_PREPARE, AC_MSG_NOTICE)
(AC_MSG_CHECKING, AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED)

(_AC_COMPILE_IFELSE, _AC_LINK_IFELSE, _AC_RUN_IFELSE)
(_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS, _AC_PROG_F77_V_OUTPUT): Use
`$as_me' instead of `configure'.
(AC_OUTPUT): Get rid of the UCA, and of the empty line when
dumping confdefs.h into config.log.
(_AC_OUTPUT_CONFIG_STATUS): Use _AC_INIT_DEFAULTS_FDS.
Print a banner.
Use AC_MSG_ERROR and AC_MSG_NOTICE.
* acgeneral.m4 (AC_CACHE_LOAD, _AC_OUTPUT_FILES, _AC_OUTPUT_LINKS)
(_AC_OUTPUT_HEADERS): Use AC_MSG_NOTICE.
* tests/semantics.at (missing templates): Adjust.
(Shell Substitutions, Assignments): these.
Move them before `Special Shell Variables'.
(Shell Substitutions): Include information on `$()' from Russ
Allbery.
AC_INIT
AC_PROG_CC
AC_LANG_COMPILER_REQUIRE
AC_PROG_CC is expanded twice, because AC_PROG_CC provides
`AC_PROG_CC', and not `AC_LANG_COMPILER(C)' as expected by
AC_LANG_COMPILER_REQUIRE.
* aclang.m4 (AC_LANG_COMPILER(C)): Instead of calling AC_PROG_CC,
require it.
(AC_LANG_COMPILER(C++), AC_LANG_COMPILER(Fortran 77)): Likewise.

Reported by Ezra Peisach.
* tests/semantics.m4 (AC_HAVE_FUNCS): New test.
* tests/tools.at (autoupdate): As a benign side effect, updating a
macro that takes no argument produces `UPDATED([])', no longer
`UPDATED()'. Adjust the test.
Autoconf's file, do it afterwards, so that Autoconf promotes the
right use, but users still can use the old names.
Of course this revealed numerous non updated uses of old macros in
Autoconf's files. Adjust them.
But for the time being, keep `define' alive for Autoconf.

* acgeneral.m4 (AC_DEFUN_ONCE): Fix the indirection to
m4_defun_once.
* m4sugar.m4 (m4_defun_once): Also define
`m4_location(MACRO-NAME)'. s/ac_warn/m4_warn/.
Use `m4_defn' to read `m4_location'.

* acgeneral.m4 (_AC_INIT_DEFAULTS): Call `_AC_INIT_PREPARE_FDS'.
(_AC_INIT_PREPARE): Don't.
(_AC_INIT_PREPARE_ENVIRONMENT, _AC_INIT_PREPARE_FDS): Rename as...
(_AC_INIT_DEFAULTS_ENVIRONMENT, _AC_INIT_DEFAULTS_FDS): these,
since they are called from `_AC_INIT_DEFAULTS', not
`_AC_INIT_PREPARE'.
(_AC_INIT_DEFAULTS_FDS): Dump `$@' in config.log, not
`$ac_configure_args' which is not computed yet.
_AC_INIT_PREPARE_ENVIRONMENT, and fixed: set `FOO' before trying
to unset it: `unset' exits 1 if the variable is not defined.
(AS_UNSET): Require it. Use `as_unset' not `ac_unset'.
* acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): Use it.
`acconfig.h', `config.h.top', and `config.h.bot'.

Display the old scheme presenting the dependencies between input
and output files.
(Changed File Names): Clarify.
* acgeneral.m4 (_AC_DIVERT, AC_DIVERT, AC_DIVERT_PUSH)
(AC_DIVERT_POP): Move to...
* m4sugar.m4 (_m4_divert, m4_divert, m4_divert_push)
(m4_divert_pop): here.
* acgeneral.m4: Adjust to use only the M4sugar macros.
Nevertheless...
(AC_DIVERT_PUSH, AC_DIVERT_POP): New wrappers around the M4sugar
macros.
(_AC_DIVERT(...)): Rename all the diversions names as...

* shell.m4 (AS_IFELSE, AS_TMPDIR, AS_UNSET, AS_MKDIR_P)

Adjust all dependencies.

Adjust the test suite.
(AC_STATE_SAVE): ... this. Save the list of all files
