Re: NFS-trouble

Hi!

I'm not sure if I posted my fix for nfs-0.50 here before, so here it is
anyway.  Without it, you cannot mount a remote machine's filesystem on
the MiNT machine.  Apply this message using patch, and recompile
mount.

BTW, I have never really had much luck using MiNT's NFS anyway, despite
these fixes...

Have fun,
