	* mmap.m4 (GCC_AC_FUNC_MMAP): New.
	* no-executables.m4 (AC_FUNC_MMAP): Renamed to GCC_AC_FUNC_MMAP.
	Change AC_FUNC_MMAP to GCC_AC_FUNC_MMAP.

libiberty/

	* Makefile.in (aclocal_deps): Add $(srcdir)/../config/mmap.m4.
	* acinclude.m4: Change AC_FUNC_MMAP to GCC_AC_FUNC_MMAP.
	* aclocal.m4: Regenerated.
