/*
  things are getting more interesting with ints, longs and pointers

  there are several different standard data models described by this table:

  +-----------+----------------------------+
  |type\model | LP64 ILP64 LLP64 ILP32 LP32|
  +-----------+----------------------------+
  |char       |  8     8     8     8     8 |
  |short      | 16    16    16    16    16 |
  |int        | 32    64    32    32    16 |
  |long       | 64    64    32    32    32 |
  |long long  |             64             |
  |void *     | 64    64    64    32    32 |
  +-----------+----------------------------+

  Win16 used LP32 (but we don't support it any longer), Win32 obviously used
  ILP32 and Win64 uses LLP64 (a.k.a. P64)

  Under Unix LP64 is the most widely used (the only I've ever seen, in fact)
