	gcc            : ChangeLog stmt.c tree.h c-common.c expr.c 

Log message:
	* stmt.c (expand_expr_stmt): Keep last_expr_value non-NULL iff
	we're interested in the result.  Use it to tell whether to
	ignore results of enclosed expressions.
	(expand_start_stmt_expr): Added new argument, and initialize
	last_expr_value accordingly.
	* tree.h (expand_start_stmt_expr): Adjusted declaration.
	* c-common.c (c_expand_expr): Adjust call.
	* expr.c (expand_expr) [EXPR_WFL]: Pass const0_rtx down if
	ignoring the result.
