TimBL asked me to pass on details of the VMS port. Although it seemed
rather tricky at the time, the actual changes for VMS are simple. Instead
of sending you the diff -c results, they can be summarised as:

1) In gui.c, #ifdef VMS to avoid including unistd.h
2) In main.c, #ifdef VMS then do not signal SIGUSR1 (ugly fix)
3) In Xresources.h I had to change all 17 point fonts to 18 point,
as the DECwindows MOTIF seems to lack them. I also changed
the anchor colour to Red instead of hex 9f, since some people's
X defaults specified a blue background, so making the anchors
invisible!
4) STRDUP was missing from VMS, and from the Ultrix system I used.
So I included a version as a separate file.

Finally, I wrote a little VMS command file that does the compile and
link for VMS systems running Multinet. This is included below, as is
STRDUP.

Procedure for making XMosaic. This procedure expects to find the
/src files in the current directory, the /libhtmlw sources in a
subdirectory [.libhtmlw] and the /libwww sources in a subdirectory
[.libwww]. This version produces an executable for Multinet TCP/IP.
UCX and Wollongong versions can be created by changing the CC compile
flag appropriately (UCX or WIN_TCP respectively).
