On 32-bit SPARC, at least, that's going to introduce a wasted 4 bytes of
padding. (UnionVal will be aligned on an 8-byte boundary, but
Parrot_Uint is only 4 bytes long.) This is, of course, not an error in
and of itself, but if any of those "dodgy" casts assume no padding, then
there will be an error.
I'll try building, but since there are 4 permutations to try (cc and gcc,
and with and without this patch) and since each build takes 1 to 2 hours
if everything goes well, it won't be until tomorrow at the earliest that
I can report anything back. (Longer, if manual intervention is required
to fix unrelated errors.)
