* acgeneral.m4 (_AC_SHELL_TMPDIR): New macro.
(_AC_OUTPUT_CONFIG_STATUS): Use it.
Use more quoted here docs to improve readability.
Compute `$me' and use it in the error messages.
Define `$configure' and `$configure_args' to avoid continuously
mixing the uses of `configure' and `config.status' evaluation in a
single line.
Define `$SHELL' and use it.
Simplify all the unjustified `[$]foo' into `$foo', the quotes
are needed only for `$[1]', `$[@]' etc.
Replace all the uses of `ac_cs_root' with files in the tmp dir of
`config.status'.
Remove a few `rm' covered by the removal of the `$tmp' dir.
Let `config.status' support `--debug'.
(_AC_INIT_PREPARE): Avoid the leading space in `ac_configure_args'.
* doc/autoconf.texi (Invoking config.status): Adjust.

(instead of nothing) when there are no positional parameters.
From Nicolas Joly.
* acgeneral.m4 (AC_CHECK_PROG, AC_CHECK_PROGS): Prefer
`$$1' to `[$]$1', `$foo' to `[$]foo', `$[1]' to `[$]1', and
`${1+"$[@]"}' to `"[$]@"'.
* acgeneral.m4 (_AC_SH_QUOTE): Don't double quote. Escape the
double quotes too.
(_AC_ECHO_UNQUOTED): Don't double quote :).
(_AC_ECHO, _AC_ECHO_N): Quote the call to _AC_SH_QUOTE.
The autoheader chain needs to be adjusted.
* acgeneral.m4 (AH_VERBATIM): Just pass two arguments to AH_OUTPUT
instead of trying to build what `autoheader' needs: let it handle
the format by itself.
* autoheader.m4: Adjust.
s,tmp/config.h,tmp/config.hin.
The adjustment revealed that `autoconf --trace' is not robust to
single quotes in its argument.
* autoconf.sh: Fix this issue.
Rename the escape `$*' as `$%'. Implement `$@'.
* doc/autoconf.texi: Adjust.

Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning
of the installation directories'.
In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.

Move --host before --build.
Fix a test on `$ac_init_help' which was not updated.

and that `./config.cache' is the traditional name of the cache file.
* install.texi: Likewise.

f77_underscore from cache variable.
(AC_F77_WRAPPERS): Get rid of ac_cv_f77_wrappers, it's useless.
Simplify the nested case-esac into a single one.

siblings.
(AH_TEMPLATE, AH_VERBATIM): Move to...

argument of the explicit AC_INIT call is lost.
* acgeneral.m4 (AC_CONFIG_SRCDIR): New macro.
(_AC_INIT_SRCDIR): Adjust.
(_AC_INIT): Pass your argument to AC_CONFIG_SRCDIR.
* libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
On my machine the former implementation takes 4mn 40s to run the
test suite. Using m4_define leads to 4mn 15s.
* acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
m4_define, not define). 4mn.
(_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you
just move NORMAL* first in m4_case, the test suite is run in 3mn.
If instead of using m4, you use an `associative array' plus a
wrapper (current implementation), it falls to 2mn.

AC_OUTPUT over quotes too: stop that.
Reported by Martin Buchholz.
* doc/autoconf.texi (Output): Don't expand on the ternary
AC_OUTPUT.
* acgeneral.m4 (AC_OUTPUT): Don't over quote $2 and $3.
* acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.
Handle the NLS envvars, and IFS.
(_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.
(_AC_WHICH_A, AC_PATH_PROG): Rely on the default IFS.

AC_TRY_LINK, AC_TRY_RUN_NATIVE): Simplify the removal of the
contest files: don't remove them before running the actions, just
remove them at the end of the macro.
* acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
variable instead of three.
Use AC_CACHE_CHECK.
Shorten the name of the var loops, they are no longer cached.
Include sys/types.h unconditionally.
`select' returns an int, fixes Autoconf/46.
Don't display parens in the user messages.
(AC_REVISION): Require AC_INIT, not _AC_INIT_BINSH.

`Setup'.
Rename as `Notices'.
Document AC_COPYRIGHT.
Don't give false reasons for placing AC_REVISION before AC_INIT,
the place no longer matters.
CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
diversion, because it is AC_OUTPUT_FILES which undiverted the
AC_SUBST sed script at its proper place, otherwise it would have
been undiverted at the end of `configure', leading to an sh syntax
error.
Now that we no longer use a diversion, we don't need to call
AC_OUTPUT_FILES if useless.
(AC_OUTPUT_FILES): Rename as _AC_OUTPUT_FILES.
(AC_OUTPUT_LINKS): Rename as _AC_OUTPUT_LINKS.
Automake calls it, and usually users do too. If it happens,
`--program-prefix=g' actually prepend two (or more) `g'.
* acgeneral.m4 (AC_DEFUN_ONCE): New macro.
(AC_ARG_PROGRAM): AC_DEFUNed_ONCE. Or is it AC_DEFUN_ONCE'd? :).
No longer AC_EXPAND_ONCE the help string, the macro itself is
expanded at most once.
Rename the here-doc tag EOF_SED as EOF.
* acgeneral.m4 (_AC_INIT_PARSE_ARGS): Stop global double quoting,
failed experiment.
Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
(AC_SUBST): Implement support for 2nd arg.
* doc/autoconf.texi (Setting Output Variables): Adjust.
Suggested by Alexandre Oliva and Lars J. Aas
* libm4.m4 (ifndef): New macro.
* acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
its value. The diversions now have a short name, e.g., `NOTICE',
instead of the former macros which had long names, e.g.,
`AC_DIVERSION_NOTICE'.
(AC_DIVERT_PUSH): Adjust.
(AC_DIVERT_POP): Use ifndef.
(AC_DIVERSION_CURRENT): Rename as `AC_DIVERT_DIVERSION' to stay
within the `AC_DIVERT' name domain.
Adjust all callers.
* acspecific.m4: Adjust all callers.
headers if they exist (needed for some missing prototypes) and
corrects the signal handler prototype/definition. The signal
handler prototype is now prepended with an `extern "C"' for C++
compilers since some platforms explicitly require an `extern "C"'
signal handler.
comment.
* libm4.m4 (m4_quote): s/$@/$*/.
* acgeneral.m4 (AC_COPYRIGHT): Prepend `# ' to the lines that goes
on the top of `configure'. Actually, prepend `@%:@ ' so that
there are as many evaluations on both sides.
(_AC_INIT_VERSION): No longer strip `# '.
`configure'. And after all, it suits to `configure --version' too.
* acgeneral.m4 (AC_DIVERSION_DEFAULTS, AC_DIVERSION_INIT_PREPARE):
New diversion numbers.
(AC_DIVERSION_INIT): Renamed as...
(AC_DIVERSION_INIT_PARSE_ARGS): this.
(AC_DIVERT_POP): Instead of going into wild endless loops when
there are more pops than pushes, die with dignity.
(AC_COPYRIGHT): New macro.
(_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
here...
(_AC_INIT_PREPARE): to here.
(_AC_INIT_NOTICE): Remove.
(AC_INIT): Use it to install Autoconf's Copyright.
(_AC_INIT_DEFAULTS): New macro.
(AC_INIT): Use it.
(AC_PREFIX_DEFAULTS): Dump in AC_DIVERSION_DEFAULTS.
(_AC_INIT_PARSE_ARGS): Dump in AC_DIVERSION_INIT_PREPARE.
* acgeneral.m4 (AC_DIVERSION_DEFAULTS): New diversion number.
(_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
here...
(_AC_INIT_PREPARE): to here.
(_AC_INIT_NOTICE): Play with your diversion yourself, don't let
(AC_INIT): do it for you.
(_AC_INIT_DEFAULTS): New macro.
(AC_INIT): Use it.
* acgeneral.m4 (AC_EXPAND_ONCE): AC_PROVIDE yourself, in case
there is no AC_DEFUN associated with the text to expand.
(_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
_AC_ARG_VAR_HELP_PROLOGUE): Remove, instead...
(AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): do it yourself.
`configure --help'.
* acgeneral.m4 (AC_DIVERSION_HELP_BEGIN, AC_DIVERSION_HELP_ENABLE,

(_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
_AC_ARG_VAR_HELP_PROLOGUE): New macros.
(AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Expand once the
_HELP_PROLOGUE macro which corresponds.
(_AC_INIT_HELP): Adjust to AC_DIVERSION_HELP_BEGIN and
AC_DIVERSION_HELP_END.
(_AC_INIT_NOTICE, _AC_INIT_HELP): Remove the sh code which handled
the optional help strings.
(_AC_INIT_PARSE_ARGS): this.
Move the display of help and version strings to...
(_AC_INIT_HELP, _AC_INIT_VERSION): here.
(AC_INIT): Adjust. Also, fix quotation.
Any character before the colon is accepted because network drives
can be assigned characters outside the [a-zA-Z] range. DOS-style
relative paths (?:foo/bar) are also considered absolute for
Autoconf's purposes since the path '../?:foo/bar' is invalid.
* acgeneral.m4 (AC_OUTPUT_FILES): Treat DOS-style paths (?:*') as
absolute.
(AC_OUTPUT_SUBDIRS): Likewise.
(AC_PATH_PROG): Make pattern for matching DOS-style paths the same
as that used in AC_OUTPUT_FILES and AC_OUTPUT_SUBDIRS.
(AC_CHECK_PROG): Use it. Use ifval.
(AC_CHECK_PROGS): Use ifval. Fix the quoting.
* tests/semantics.m4: Test AC_CHECK_PROG.
* tests/Makefile.am (EGREP_EXCLUDE): Add /AC_CHECK_PROGS?/.
