I'll be glad when this 32-bit cruft can be removed. It is *very* confusing to 
read the code and see a function called getuid that is really only used by old 
applications, except when it's accidentally used internally. I introduced a 
32-bit-only bug a couple years ago because of a similar confusion between fstat 
and fstat64.
