	* diagnostic.c (finish_abort): Deleted.
	(fatal): Add code from fninish_abort.
	(error_recursion, fancy_abort): Call fatal, not finish_abort.
	(trim_filename): Remove leading "../".
	* diagnostic.h (finish_abort): Deleted.
	* toplev.c (crash_signal): Call fatal, not finish_abort.

	* stor-layout.c (place_field): Treat overflowing DECL_SIZE_UNIT
	as if size were variable.

	* expmed.c (expand_mult): Write REG_EQUAL note with proper mode.
