Fortunately, it's not as bad as /that/. While it's true that python
inherits the integer size from the compiler, it doesn't use C's int to
implements python ints, but C's long and thus can guarantee a precision
of at least 32 bits. Also, due to seamless conversion (see my other post
<http://www.ietf.org/mail-archive/web/vwrap/current/msg00862.html>) to
python's (unlimited precision) long, the actual size of python's int (or
the implementation dependence of that size) can probably be ignored most
of the time, except maybe for performance considerations.
