Yes, I took your patch from sourceforge.  Many thanks: I applied it to
the debian package.


One thing I was wondering about is the license.  Geomview uses
the LGPL, while the new file "src/lib/oogl/util/seekpipe.c" created
by Claus-Justus is provided under the GPL.  I don't know what
a mixture of GPL and LGPL would mean.  For debian, I opted to
invoke LGPL clause #3 and declare the whole of geomview under
the GPL.

For the CVS on sourceforge, I guess it would make sense to decide
which license is desired for geomview and either change seekpipe.c to
LGPL or change the rest of geomview to GPL.
