Hi there, thanks to all replies.

Sorry, my mistake. Type is uint32_t.

I'm getting a compiler error with gcc 3.4.5. The compiler that comes with MinGW.

I know about using enums for such a case. But it used to be a matter
of taste since MS compiler works just fine. Seems like now it's a
necessity to use enum. I was wondering how other boost libs do it?
