(Which both are healthy and important to deal with, the GPL just
requires a bit of disciplin to ensure freedom in the future.)
Can the code be linked together with GPL code?
(For this matter is has to permit everythink that is connected
with free software, but it does not have to be as save as
software under the GPL.)
PD if used in a context is okay and you can even claim the
copyright, if we changed it for the sake of grass development.
So it is GPLable in a way. ;-)
The second is: Non-free software or almost free software
cannot be linked to GPL programs.

gnuplot is not GPL. In fact gnuplot has nothing to do with the GNU
project. The name is pure coincidence. Gnuplot is almost free-software
(99.9%). So it depends on who wrote the code.
