I've read that, but I still don't understand why _use_lfn would not
suffice.  I think that is what you ned.

No, not really: all Windows flavors of the NT family present
themselves as DOS 5.5.  Only Windows 9x and ME report correct DOS
versions (7.x).

However, the question is: do you at all care to distinguish between
Windows 2000 and XP, and if so, why?

No problem here, you can simply bind your program with CWSDPMI.

I don't know how best to test that.  Perhaps try invoking `ping' to
ping some known Internet address.
