My thoughts are this guy is type of the developer I hate to work with most. The style and naming Windows and Borland C++ specific, so this probably grew organically from Win3.1/NT. This probably pre-dates STL, but holy cow. Given how he misuses some terminology, he is probably a self-taught programmer from days of old.
Generally, when I see that a developer has decided to use their own typdefs to represent intrinsic data types, it's a bad sign. However, what I see that this guy created his OWN class as a replacement for bool, I know I'm going to be rewriting a lot of code.
There is no way I would use this library, regardless of the terms.
