What problems do you see compiling this with the current headers?  I'm
not having problems compiling this example.

Ok, I agree that TEXT is incorrect.  But the definition of _T I don't
believe to be incorrect.  However, the MSDN documentation describes this
macro for tchar.h not for winnt.h.  The macro is correct for tchar.h.

Your patch has problems:
1) you did a reversed patch
2) you don't include a ChangeLog entry.

I will take care of modifying w32api/include/winnt.h and give you credit
for pointing it out.

Earnie.
