Update for autoconf beta 1.112:
* 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.
