Thanks ysth for having a look..
It is really nice to know that I am not doing something
silly ( though if I was it would be much easy to fix ;-) ).
It seems to me that be the libpgplot.a libary file may be calling GrWin routines (GWgetrgb
and varrious others) and are looking for them in the gwdriv.o or gwdriv.c files.
When I search for these files they have not been down loaded as part of the GrWin driver.
