Real quick question: 
Is there a #defined symbol which will tell me "Hey, you are on windows NT"?

Reason I think that I need it:
I have a project with lots of files, mostly being worked on under unix. 
Part of the work, my part, will be done under NT.
Many of the files are not in the 8.3 DOS format expected by make under NT.
If I could detect NT or even DJGPP, I could say (for example):

#if defined _WIN_NT_
#include "Longfilename.blah.cpp"
#else
#include "Longfi~3.bla"
#endif

I know this is a very awkward workaround, but at this point, it's better 
than trying to reorganize the whole project around 8.3 filenames. If 
there's a much better workaround, I'd LOVE to hear it.
Thanks.

Please (cc) me a copy of your response, if possible.
