DJGPP defines `unix' and `__unix__' for a good reason.  Some ported 
utilities use that symbol for code that DJGPP uses, and will break if you 
remove them.  Since DJGPP is highly Posix-compliant, defining `unix' 
seems appropriate.

I think your decision to use `unix' as the condition for Unix-only code 
is flawed.  You should use __DJGPP__ for the DJGPP-specific stuff, like 
the FAQ suggests.

Use the -dM switch to the compiler.
