* acgeneral.m4 (_AC_INIT_SRCDIR): New macro, pulled out from...
(_AC_INIT_PREPARE): No longer compute `srcdir'.
(_AC_INIT): Use _AC_INIT_SRCDIR.
(AC_INIT): Don't forget to pass the argument to _AC_INIT.
* acgeneral.m4 (AC_PACKAGE): New macro.
(_AC_COPYRIGHT_SEPARATOR): Remove.
(AC_COPYRIGHT): Adjust.
(_AC_INIT_HELP, _AC_INIT_VERSION): Name the package you configure
when you want.
(_AC_INIT): Adjust.
* configure.in (AC_PACKAGE): Add.
of $ac_xdir. Not only is `test -e' not portable, but the test isn't
necessary at all; the following mkdir ends up accomplishing the
same goal. Suggestion from Alexandre Oliva.
record, this is not portable: mawk and nawk understand it as RS =
"". gawk understands it as expected.
* autoconf.sh (translate_awk::BEGIN): No longer change RS.
(translate_awk::body): Move to the END.
Instead, accumulate the input in `request'.
arguments, AC_OUTPUT arguments 2 and 3 were not! Currently,
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.
* acspecific.m4 (AC_PROG_INSTALL, AC_FUNC_SELECT_ARGTYPES):
Likewise.
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.
(m4_case,m4_match): Rewrite to use m4_shiftn (for readability reasons).
(m4_for): Add the STEP argument and some argument-verifying asserts.
(m4_split): Correct spaces to tabulator in regexp.
* 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.
(AC_INIT): Do what _AC_INIT_BINSH used to.
Don't require _AC_INIT_VERSION, just call it.
Rename as _AC_INIT.
(AC_INIT): New macro, single expansion wrapper around _AC_INIT.
(_AC_COPYRIGHT_SEPARATOR): New.
(AC_COPYRIGHT): Use it.
Require AC_INIT, not _AC_INIT_VERSION.
* doc/autoconf.texi (Versions): Promote as first section of
`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.
file names.
(translate_awk::BEGIN): Set RS to "0" so that the whole file be a
single record.
(translate_awk::trans): Convert from array to function.
(translate_awk::error): New function.
(translate_awk::main action): Implement support for ${sep}@ and
${sep}*. Use trans() and error().
(translate_awk): Don't put space before user functions call, it is
not portable.
Remove trailing `;', this is not C :).
(task trace): Quote `$traces' when you eval it, to protect the
white spaces.
Propagate `translate_awk' failures to `autoconf.sh'.
Translate the quadrigraphs.
* 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.
