The fact that it actually is not correct. We want to determine
the size in bits of the CPU registers.

Here's what I know:

                      sizeof(int)     sizeof (long)
   ---------------+----------------+-----------------
   32 bit Linux   |       4        |       4
   64 bit Linux   |       4        |       8
   32 bit windows |       4        |       4
   64 bit windows |       4        |       4

Note that sizeof(long) on 64 bit windows is 4!

Most other unixen follow the LP64 scheme used by Linux.
