This has been discussed several times here and on the Sourceforge
bug-tracking pages.  Basically the reason is that Red Hat 7 ships with
a most unstable version of libc, along with a most unofficial and most
unstable version of GCC.  The name GCC 2.96 in itself is wrong, since
it is not even a released GCC snapshot but a development version taken
at time t from the CVS tree (or something like that).  Those two in
combination (GCC + libc) trigger a bug defining LONG_BIT to be 64 even
on i386 machines, which is detected by the Python code.  The error
being in GCC+libc, the Python code does not try to fix it.  It stops
compilation instead.
