!! this dosemupatch is _not_ needed for kernel >= 1.3.71 :)  !!
If dosemu don't work together with mars_nwe you should apply
the dirty dosemu-patch to the dosemu program.
In 1.3.6? the changing of an existing route over the internal net
is not ignored, but handled as an error (EINVAL, Alan's idea :-( ) .
Therefor actual dosemus can fail when then want to access a external
server.
