I took the `x86-linux' stuff and ported it to DJGPP (DOS) using
`malloc' instead of `mmap', and fixed (commented out) a couple of
lines of assembler, and it seemed to work fine.  Then I compiled the
same source under Mingw32 (Windows) and it seemed to work too.

I'll send a patch soon.  Only problem is the build system doesn't
work without Unix tools (which I have but others probably won't).
