Actually, the real problem is the Microsoft compatibility with  
Microsoft :-))
It's always a significant (and painful) effort to 'port' Visual Studio  
6 code to Visual Studio 2005. There are always some API changes and  
some unexpected behavioral changes, resulting in hours of debugging or  
of trying to understand enigmatic compilers errors.

if it works, it's the solution. Anyway, the debugdevice.h is only  
present for your debug purpose.

you're probably right. But before that, I'd prefer to support gnu  
compiler (via mingw). I'll try to see what I can do in a near future.
Is 'debugdevice.h' error the only one when compiling with 2005?
