mmap() and munmap() are posix functions. Since DJGPP
doesn't include all of posix (because DOS doesn't have
the basic functionality) you probably won't find it
easy to port this program using DJGPP. 

Use Cygwin instead. Cygwin emulates posix in a Win32
environment. Goto Cygnus software's web page:
