Hmm, maybe you should find out?  It works fine for me.

Note that just about all RSXNT programs use load time DLL
linking IIRC -- all of the C library is in a DLL.  I think
unless you switch this off, your application will load RSXNT.DLL
at load time.

I have no idea what you're talking about; but I don't use getopt
etc.

That's pretty much what I've done (see my other email about
this) but I didn't use the winsock.h that comes with RSXNTDJ.
Everything works fine for me so far.

Have you tried debugging it?  See the RSXNTDJ docs for
information on this.
