Full 64 bit support (i.e. "long long"). Things to consider:
how to store/retrieve 32+ integers into/from Perl scalars?
32+ constants in Perl code? (non-portable!)
to be used in re-entrant (=multithreaded) code.
Icky things: the _r API is not standardized and
the _r-forms require per-thread data to store their state.
