This wouldn't be a problem if the ports were part of the GPC distribution
just as they are with DJGPP (and EMX?).

I am not sure what this means. If it means writing the code for DOS
and CRT from the scratch, I wouldn't want to be the one to do that!

AFAICS the unix version is not in the DOS version, otherwise I would
have used it (I tried to use only portable C functions in the SYSTEM 
unit). The problem is that itoa() exists in DJGPP and EMX (and perhaps
CYGWIN) but not in unix/Linux. If there is a function in the unix/Linux
C libraries that does the same thing, that function does not exist in 
DJGPP, so it cannot be used there. I cannot see any solution other
than an IFDEF here!
