If you need to write code that is only compiled on DJGPP, use the 
__DJGPP__ symbol (like in "#ifdef __DJGPP__").  Other platforms have 
their own symbols, but that is specific to each platform.

You can see what does GCC define automatically by looking at the `specs' 
file that exists on every GCC installation (for DJGPP, it is in the lib/ 
subdirectory).
