Thank you for the pointer.  That seems directly on point, and makes C99
match the existing GCC practice: we don't need to worry that pointers
might point to unions.

Gaby, would you please forward that to the C++ reflector, so that the
reflector has that information as well?  They should be aware that the
model you're proposing is at odds with C99.

Thanks,
