  UINT{7,15,31} declarations state that variables either are not used
  arithmetically or, when they are, that they are never going to contain other
  than small positive integers.  Ranges:
    UINT7	0..127 arithmetic		8 bit non-arithmetic
    UINT15	0..32767 arithmetic		16 bit non-arithmetic
    UINT31	0..(2**31-1) arithmetic		32 bit non-arithmetic

  SINT{8,16,32} declarations state that variables will contain both positive and
  negative integers.  Ranges:
    SINT8	-128..127 arithmetic		8 bit non-arithmetic
    SINT16	-32768..32767 arithmetic	16 bit non-arithmetic
    SINT32	-(2**31)..(2**31-1) arithmetic	32 bit non-arithmetic

  UINT{8,16,32} declarations state that variables will contain the full
  possible positive range of numbers in the given size.  Ranges:
    UINT8	0..255 arithmetic		8 bit non-arithmetic
    UINT16	0..65535 arithmetic		16 bit non-arithmetic
    UINT32	0..(2**32-1) arithmetic		32 bit non-arithmetic

  UINT{7,15,31} should be the most used declarations.  They may be implemented
  as either signed or unsigned types in different environments.
  
  SINT{8,16,32} and UINT{8,16,32} should only be used when the range beyond
  that of UINT{7,15,31} is required.  In some environments some of SINT{8,16,32}
  and UINT{8,16,32} may not be available.

  In early C implementations "unsigned" is a type, not a modifier to a type,
  so only UINT16 ("unsigned int") is available.  UINT32 and SINT8 (on Lattice)
  or UINT8 (on v7 Unix) are not available at all.

  On the following systems (at least) "unsigned" is a modifier:
    IBM Instruments System 9000 Xenix 2.3D
    IBM Personal Computer Xenix 286 v1.00 (3.14)
    Convergent Technologies Megaframe CTIX 2.1
    Convergent Technologies Miniframe CTIX 3.05
    Honeywell Scorpion System III 3.3
    Berkeley Standard Distribution 4.2

  Set -D_STRICT_ in your lint or cc to exclude typedefs unavailable
  on your machine.
