Stop using variables for tmp files, use their names in $tmp.

AC_LANG_CALL(FORTRAN77)): New macros.

(AC_TRY_CPP): Argument was output twice.
(AC_COMPILE_IFELSE, AC_LINK_IFELSE): Output $3 only if needed.

* acgeneral.m4 (_AC_LANG_DISPATCH): New macro.
(AC_LANG): Use it.
(AC_LANG_SOURCE, AC_LANG_SOURCE(C), AC_LANG_SOURCE(C++),
AC_LANG_SOURCE(FORTRAN77)): New macros.
(AC_TRY_COMPILER, AC_EGREP_CPP, AC_TRY_RUN_NATIVE): Use

be used before AC_INIT, but they do require it. But then, the
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.
* acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Prefer
for i in : $is; do test $i = : && continue
over
for i in .. $is; do if test $i != ..; then
* 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.

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 =

* autoconf.sh (translate_awk::BEGIN): No longer change RS.
(translate_awk::body): Move to the END.
Instead, accumulate the input in `request'.

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.
