Such type should be used as parameter for all functions which accept
it.

Why? You should ask on some MFC forum.

library is to provide new integer types, although it is usually
absolutely unnecessary (exception may be processing of some binary
data). Such types aren't usually placed in any project/library specific
namespace, so it usualy contains some prefixes to distinguish library
32-bit integer from other 32-bit integers (like ABCv37_INT32).

situation and we have to live with it.

Microsoft likes to give existing things new names.

Microsoft decided it was too easy to write portable code, so it helped
us out by renaming all the primitives...
