2006-01-04 Paolo Bonzini <bonzini@gnu.org>

	PR bootstrap/24252

	* Makefile.def (flags_to_pass): Add STAGE1_CFLAGS and STAGE1_LANGUAGES.
	* Makefile.tpl (OBJDUMP): New.
	(EXTRA_HOST_FLAGS): Add it.
	(EXTRA_GCC_FLAGS): Remove flags already specified in flags_to_pass.

        * Makefile.tpl (stage[+id+]-start, stage[+id+]-end): Do not try
        to use symbolic links between directories.  Avoid race conditions
        or make them harmless.
        * configure.in: Do not try to use symbolic links between directories.

	* Makefile.def (LEAN): Pass.
	* Makefile.tpl (LEAN): Define.
	(stage[+id+]-start): Accept that the previous directory does not
	exist, if the bootstrap is lean.
	(stage[+id+]-bubble): Invoke lean bootstrap commands after
	stage[+id+]-start.  Use a makefile variable and an `if' instead of a
	configure substitution.
	([+compare-target+]): Likewise.
	([+bootstrap-target+]-lean): New.
	* configure.in: Remove lean bootstrap support from here.

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