	Sync from gcc.

	2005-02-28  Paolo Bonzini  <bonzini@gnu.org>

	PR bootstrap/17383
	* Makefile.def (target_modules): Remove "stage", now unnecessary.
	* Makefile.tpl (HOST_SUBDIR): New substitution.
	(STAGE_HOST_EXPORTS, EXPECT, HOST_LIB_PATH, USUAL_AR_FOR_TARGET,
	USUAL_AS_FOR_TARGET, USUAL_DLLTOOL_FOR_TARGET, USUAL_GCC_FOR_TARGET,
	USUAL_LD_FOR_TARGET, USUAL_NM_FOR_TARGET, USUAL_OBJDUMP_FOR_TARGET,
	USUAL_RANLIB_FOR_TARGET, USUAL_WINDRES_FOR_TARGET): Use it.
	(Host modules, Bootstrapped modules): Use it.
	(Build modules, Target modules): Do not create symlink trees,
	always configure out-of-srcdir.
	(distclean): Try removing $(host_subdir) with rm before using rm -rf.
	* configure.in (FLAGS_FOR_TARGET, CC_FOR_TARGET, GCJ_FOR_TARGET,
	GFORTRAN_FOR_TARGET, CXX_FOR_TARGET, RAW_CXX_FOR_TARGET): Use
	$(HOST_SUBDIR).  Create a symlink for host_subdir.

	* Makefile.in: Regenerate.
	* configure: Regenerate.

	Merged from libada-gnattools-branch:
	2004-11-28  Nathanael Nerode  <neroden@gcc.gnu.org>

	* Makefile.def: Add gnattools as a module, depending on target-libada.
	* Makefile.in: Regenerate.
	* configure.in: Include gnattools in host_tools; disable it if ada
	is disabled.
	* configure: Regenerate.

config:
2005-02-28  Paolo Bonzini  <bonzini@gnu.org>

	PR bootstrap/17383
	* acx.m4 (GCC_TOPLEV_SUBDIRS): Set HOST_SUBDIR if an in-src
	gcc build is going.
