c-typeck.c (c_expand_start_case): Return immediately if exp is an ERROR_MARK.

1999-08-27 00:27 -0700  Zack Weinberg  <zack@bitmover.com>

	* c-typeck.c (c_expand_start_case): Return immediately if exp
	is an ERROR_MARK.
	* fold-const.c (operand_equal_p): Return immediately if arg1
	or arg0 are ERROR_MARKs.
	* stor-layout.c (layout_type [case RECORD_TYPE]): Ignore
	fields of type ERROR_MARK when calculating if the record can
	go in a register.
