Subject: [PATCH] 2005-12-19  Paolo Bonzini  <bonzini@gnu.org>

	* configure.in: Select appropriate fragments for PowerPC/AIX.
	* configure: Regenerate.

	* Makefile.def (flags_to_pass): Add ADAFLAGS, BOOT_ADAFLAGS,
	BOOT_CFLAGS, BOOT_LDFLAGS.
	* Makefile.tpl (POSTSTAGE1_FLAGS_TO_PASS): Handle BOOT_ADAFLAGS,
	BOOT_CFLAGS, BOOT_LDFLAGS.
	(TARGET_FLAGS_TO_PASS): Handle ADAFLAGS_FOR_TARGET.
	(stage[+id+]-bubble): Pass flags recursively to the comparison target.
	(stage): Fail if we cannot complete the work.

config:
2005-12-19  Paolo Bonzini  <bonzini@gnu.org>

        * mt-ppc-aix, mh-ppc-aix: New.
