That's wrong, IMO.  If anything change them to int32_t.  The overhead of
int64 is unacceptable on many of the older platforms.  If you are going to
make things compat32 friendly, that's fine.  but don't make things worse
for platforms that will never use compat32.

Personally, I think if you are going to run 32bit programs on a 64bit
platform, you should expect a little performance hit.
