* 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
