  30  * Win32 was easy to implement under Unix since most 32-bit Unices use the same
  31  * type model (ILP32) as Win32, where int, long and pointer are 32-bit.
  32  *
  33  * Win64, however, can cause some problems. Most 64-bit Unices use the LP64 type
  34  * model where int is 32-bit and long and pointer are 64-bit. Win64 on the other
  35  * hand uses the LLP64 type model where int and long are 32 bit and pointer is
  36  * 64-bit.
