aclocal.m4 (libiberty_AC_FUNC_C_ALLOCA): New.
libiberty:
* aclocal.m4 (libiberty_AC_FUNC_C_ALLOCA): New.
* configure.in: Replace all alloca logic with a simple use of
the above new macro.
* config.table: Kill *-*-beos* entry.
* config/mh-beos: Delete.
* configure, config.in: Regenerate.
* Makefile.in (ALLOCA, HFILES): Kill.
(REQUIRED_OFILES): Add alloca.o.
(alloca.o): Depend on libiberty.h.
(argv.o): Don't depend on alloca-conf.h.
* alloca-conf.h: Delete.
* alloca.c: Include libiberty.h. Kill all #ifdef emacs
blocks. Provide the C alloca unconditionally. Use PTR where
appropriate. Make i00afunc static.
* argv.c: Don't include alloca-conf.h.
include:
* libiberty.h: Prototype C_alloca; define alloca to either
__builtin_alloca or C_alloca as appropriate.
gcc:
* aclocal.m4 (AM_GNU_GETTEXT): Don't AC_REQUIRE
AC_FUNC_ALLOCA.
* configure, config.in: Regenerate.
* config.gcc: Remove references to deleted files.
* genattr.c, genattrtab.c, genextract.c, genoutput.c,
genrecog.c, rtl.c: Do not use alloca anywhere.
