This one should now work with GCC and other real-world compilers. It's still
not valid C because the C standard explicitly does not require a union to be
100% overlapping storage (if you assign one member, the value of the other is
undefined), in fact handling "union" as "struct" would still be a compliant
implementation of "union". But GCC *does* guarantee that you can use "union"
that way and other compilers in practical use do as well.
