  Some rules about types:
  - do not use Ulong, these are not portable.
  - do not use the constants, UINT_MAX, INT_MAX and INT_MIN
  The following are the assumptions about the types:
  - size(Uint) >= 4
  - size(Sint) >= 4
  - size(Ushort) = 2
  - size(Sshort) = 2
  No other assumptions are to be made.
