There are probably implementations that don't support this.
However, in ANSI C functions can return (rvalue) structures.
Since the function value is not an lvalue, neither will the
result of the member-of operator be an lvalue.  Thus,
	sfunc().member = a;
is invalid.  (There should be no such problem with structure
pointers and ->.)
