Subject: 	* gimplify.c (gimplify_compound_lval): Treat REALPART_EXPR and
 	IMAGPART_EXPR the same as COMPONENT_REF. 	* tree-simple.c
 (is_gimple_addr_expr_arg): Ditto. 	(is_gimple_lvalue): Remove
 REALPART_EXPR and IMAGPART_EXPR. testsuite 	*
 gcc.c-torture/execute/20030910-1.c: New test. 	*
 gcc.g-torture/compile/20030910-1.c: New test.
