	gcc            : c-decl.c ChangeLog 

Log message:
	Remember a tag type across compilation units.
	* c-decl.c (TYPE_IS_OLD_TAG):  New macro.
	* c-decl.c (restore_fragment_bindings):  Chain new decl after old one.
	When restoring a tag, reuse old tag type, and clear TYPE_IS_OLD_TAG.
	(poplevel):  If popping a global tag, keep the IDNTEFIER_TAG_VALUE,
	but hide it using TYPE_IS_OLD_TAG.
	(lookup_tag, shadow_tag_warned, xref_tag, start_struct, start_enum,
	finish_enum):  Handle TYPE_IS_OLD_TAG.
	
	* c-decl.c (pushdecl, lookup_name, finish_enum):  Use new
	track_declarations global.
