The only difference there is that an INTEGER is referred to as a "32 bit integer" and a LONG is referred to as a "32 bit long integer". In C++, doesn't the suffix UL mean unsigned long, while L simply means long (and possibly signed)?

George, from the API position, there is no unsigned long, so we emulate as necessary. Typical references, a LONG is signed, a ULONG is unsigned.
