What about apr_int32_t in 1.3 - provided we determine it's legit?

On top of that, extend it with a second apr_int32_r reserved which would be
a simply memory placeholder to prevent a 64-bit size from overwriting the
extent of the original size?  We could even make this conditional on int
being 64 bits.

So sparc/risc/ppc families are as broken as they currently are until being
rebuilt against the fix, while the others should be binary compatible w/o
a recompile.
