* aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New macros.
* configure.in: Use them. Use AC_ARG_PROGRAM (now provided by autoconf)
instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move test for CROSS_COMPILE
just before AC_FUNC_ALLOCA, and emit a message to try to ease confusion about
autoconf's "cross-compiling" message.
* acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.
* configure, conf.in: Regenerated.
* aclocal.m4 (AC_OUTPUT_LINKS): Deleted redefinition, since autoconf 1.109 has
this fixed.
* configure.in: Don't change quote characters around AC_MSG_ERROR invocation.
Don't use AC_HEADER_STDC, since it requires running a program. Cache
NEED_*_DECLARATION values.
* configure, conf.in: Regenerated with a modified autoconf 1.109.
* acconfig.h, aclocal.m4: New files.
* configure.in: Rewritten (except for some target-specific code) for autoconf.
* conf.in, configure: New files, generated from the above.
* Makefile.in: Changed magic sequence indicating insertion of makefile
fragments.
(VPATH, srcdir, CC, LIBS, OBJS dependencies): Use @-substitutions from
configure.
(LINKED_HEADERS): Deleted a.out.gnu.h, a.out.h, and host.h.
(config.status, configure): Rewrite rules.
(config-stamp): Depend on conf. Skip variables that configure is now
substituting itself.
(*.o dependencies): Deleted host.h.
(distclean, realclean): Don't delete host.h.
* as.c: Don't include stdio.h, string.h, sys/types.h. Include signal.h after
as.h.
* as.h: Include alloca-conf.h first. Include ctype.h, string.h, strings.h,
stdlib.h, unistd.h, sys/types.h, fopen-bin.h, fopen-same.h, as suggested by
autoconf test results.
[BROKEN_ASSERT]: Don't include assert.h.
(strdup): Declare.
(volatile, const): Define if not __STDC__ and not already defined.
(malloc, realloc) [NEED_MALLOC_DECLARATION]: Declare.
(free) [NEED_FREE_DECLARATION]: Declare.
* gasp.c: Include config.h, stdlib.h (if HAVE_STDLIB_H). Don't include host.h.
(malloc) [NEED_MALLOC_DECLARATION]: Declare.
* messages.c: Include as.h first. Include errno.h only if HAVE_ERRNO_H. If
HAVE_VARARGS_H and not __STDC__, undefine HAVE_STDARG_H. Set NO_STDARG and
NO_VARARGS as appropriate.
* doc/Makefile.in (srcdir, INSTALL, INSTALL_PROGRAM, INSTALL_DATA): Use
autoconf @-substitutions.
