AAfter some detective work it turned out these functions are a part of XShm.c
iin the /usr/lpp/X11/Xamples/extensions/lib/ directory and archived into a
llibrary called libXextSam.a in the same directory to be linked in /usr/lib/X11
if installed.  I went ahead and built libXextSam.a and placed it in the
GGeomview/lib/x11 directory.  Adding -lXextSam at the end of the Makefile in
GGeomview/src/bin/geomview/x11/O.x11/ resulted in a stable executable.  I had
pppreviously added -lXextSam to Geomview/makefiles/mk.6000 which resulted in
fatal errors when attempting to modify polygon color properties.

II hope this helps in assisting other RS6000 users with building Geomview.
