#ifdef MY_APPOLOGY

I originally intended to make minimal modifications to the BSD 5.0 headers.
The plan was to include type definitions here that would prevent the need
to make global replacements of type definitions.

HOWEVER, below there are five (5) definitions of a USHORT - and more for
char, int, long...

This nomenclature is probably valuable to some folks. However, I grew tired
of it early on and just did global search-and-replace. In the end there
are only UCHAR, USHORT, UINT and ULONG.

If I had a little more time I would have probably adopted the .NET type
definitions.
