SCO OpenServer 5.0.4 and vncserver

[Warp]

I have successfully compiled vncclient under SCO OpenServer, but I am having
some trouble with compiling Xvnc.

Some libraries are missing from the distribution, and I am using X11R6.2
which also does not have this files.

What is Xvnc based on; X11R6.x or XFree86?  And how do I get around the
likes of....

makedepend: warning:  access.c, line 94: cannot find include file
"sys/sockio.h"
        not in sys/sockio.h
        not in ./sys/sockio.h
        not in ../include/sys/sockio.h
        not in ../../../include/X11/sys/sockio.h
        not in ../../../lib/Xau/sys/sockio.h
        not in ../../../include/sys/sockio.h
        not in ../../../lib/xtrans/sys/sockio.h
        not in /usr/include/sys/sockio.h

for example.
