 * is required, these type defines should then be used.  This will make
 * porting to systems that have different sized data types easier.
 *
 * Note: The type defines should just mean that the data type has at
 * least that many bits.  if a uint16 is actually 32 bits, no big deal,
 * it is just a waste of space.
 *
 * Note2:  When using something that is normally stored in a character
 * (ie strings), don't use the uint8/sint8 typdefs, use 'char' instead.
 * The signedness for char is probably not universal, and using char
 * will probably be more portable than sint8/unit8
