I do the same as before and get the same error. And yes, I am using Visual Studio 7.1 in case anyone thought else. What am I doing wrong?

No idea, but you can only get the error you are seeing if __BORLANDC__ is defined, and it clearly should not be if you are using Visual C++.

You're right. __BORLANDC__ was defined somewhere in this old legacy code base that is now being compiled with .Net 7.1. It didn't cross my mind. Thanks! -- Daniel
