DJGPP doesn't provide the functions `mmap' and `munmap'.  These
functions require functionality that is only supported by DPMI v1.0
spec, and most DPMI servers out there only support v0.9 functionality.

You will have to find a way to compile this program without these
functions.  If the package has some #define that can be used in
environments which don't support `mmap' (not all Unix systems do),
then simply add the appropriate -Dfoo option to the compilation
command line.
