  33  *
  34  * Win64, however, will cause some problems when implemented under Unix.
  35  * Linux/{Alpha, Sparc64} and most (all?) other 64-bit Unices use
  36  * the LP64 type model where int is 32-bit and long and pointer are
  37  * 64-bit. Win64 on the other hand uses the P64 (sometimes called LLP64)
  38  * type model where int and long are 32 bit and pointer is 64-bit.
