* autoheader.sh: s/-eq/=/.
Uniform ordering of variable initializations, option handling.
Don't use quotes where useless (foo=$1, not foo="$1").
Propagate `run_m4' and `run_m4f'.
Use `$0' in --help.
* autoconf.sh: Likewise.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: Likewise.
* autoupdate.m4: Small bug: at the end `dnl' is disabled, so use
`m4_dnl'.
* autoconf.sh (initialization): New var, new option.
(option loop): When you need an arg, make sure there is one.
(run_m4f): New var, which content is that of the former...
(run_m4): Don't use m4 frozen state files.
Change all callers.
Don't pass AC_LOCALDIR, not documented, and unused.
(task trace): Honor `--verbose' and `--initialization'.
(globally): Send `--verbose' messages in stderr.
Fix random typos.
* autoconf.sh (debug): New var, new option.
Adjust the trap code.
(task trace): Instead of decoding `m4 --trace' with sed, decode it
with m4 itself.
($silent_m4): New file, which disables m4's `errprint'.
($trace_m4): New file. Logistic for the m4 which is in charge of
decoding the traces of the first.
($translate_awk): Transform a user trace request into $trace_m4
code.
2.5.1 only the last one is honored:
> echo "foonbar" | egrep -e 'foo' -e 'bar'
bar
> echo "foonbar" | egrep -e 'bar' -e 'foo'
foo
Reported by Nicolas Joly.
An alternative would have to use `sed', unfortunately alternation
is not portable.
* tests/actest.m4 (join): New macro.
(AC_ENV_SAVE): Join the egrep patterns into a single big one.
* tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
Join the egrep patterns into a single big one.
headers if they exist (needed for some missing prototypes) and
corrects the signal handler prototype/definition. The signal
handler prototype is now prepended with an `extern "C"' for C++
compilers since some platforms explicitly require an `extern "C"'
signal handler.
comment.
* libm4.m4 (m4_quote): s/$@/$*/.
* 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.

there are more pops than pushes, die with dignity.

here...
(_AC_INIT_PREPARE): to here.
(_AC_INIT_NOTICE): Remove.
(AC_INIT): Use it to install Autoconf's Copyright.

(AC_INIT): Use it.

* 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): 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_DIVERSION_HELP_WITH, AC_DIVERSION_HELP_VAR,
AC_DIVERSION_HELP_END): New diversion numbers.
(AC_EXPAND_ONCE): New macro.
(AC_PROVIDE_IF): New macro.

(AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Expand once the
_HELP_PROLOGUE macro which corresponds.

the optional help strings.

* tests/atspecific.m4 (AT_TEST_MACRO): Set AC_CONFIG_AUX_DIR to
top_srcdir in configure.in, and pass the value of top_srcdir to
configure.
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.

* tests/semantics.m4: Test AC_CHECK_PROG.
* tests/Makefile.am (EGREP_EXCLUDE): Add /AC_CHECK_PROGS?/.
