 * Win32 was easy to implement under Unix since most (all?) 32-bit
 * Unices uses the same type model (ILP32) as Win32, where int, long
 * and pointer are 32-bit.
 *
 * Win64, however, will cause some problems when implemented under Unix.
 * Linux/{Alpha, Sparc64} and most (all?) other 64-bit Unices use
 * the LP64 type model where int is 32-bit and long and pointer are
 * 64-bit. Win64 on the other hand uses the P64 (sometimes called LLP64)
 * type model where int and long are 32 bit and pointer is 64-bit.
