+    	* mathod.c (build_opfncall): Don't call build_new_op in case of 
+    	MODIFY_EXPR even in ansi overloading rules are specified. This fixes 
+    	the compilation of the follwing code snipplet:
+    	    struct {
+	      int bit1:7;
+	    } b;
+	    enum { val1 = 0x0f };

+	    {
+	      b.bit1 |=  val1;
+	    }

 	* typeck.c (expand_target_expr): Make definition match declaration.
