Neal,

I just tested this out last night and it already achieves this (on reasonably modern compilers ;-)

There should still be some differences, because of the ABI. C++ compilers usually use a mangled C ABI, which behaves differently for struct or class types, even if those have the same size and alignment requirements as some other built-in types.
