// since our name-space conflicts with standard C, we do not actually
// make a typedef. these lines are included in this file as a
// reference for the programmer of the base classes.

// the above types do not specify sizes, but there are minimum
// guarantees based around a 32 bit architecture model. a short
// integer will be at least 16 bits, long 32 bits, llong 64 bits. a
// float will be at least 32 bits, a double at least 64 bits. any data
// in excess of these limits will not be preserved thorough file
// i/o. these integral types will not have corresponding scalar
// classes and will not be included in more complex data types, or
// used in any manner except i/o or possibly fixed point. it is the
// programmers responsibility to convert data from these size specific
// data types to the more general standard integral types listed above
// before processing.
