Um, do you _really_ want to evaluate "some_expression" twice?
And how do you expect this to work when I have
	struct complex Cadd(x, y) struct complex x, y; {
	    struct complex s; ... return s;
	}

If it's just for your own use, you could pick up the sources of Alan Holub's
C compiler for US$60 and modify it to act as the processor you want.
You really do want your tool to understand C types so that it doesn't try
to cast structs to longs.  And if you want to catch all returns, you don't
want to miss the implicit one at the end of a void function.
