Comment(by hamish):

 Hi,

 patch attached for review.

 missing from it, but done locally: autoconf'd ./configure (too big), added
 $(OMPLIBPATH) to Grass.make, added $(OMP..) to lib/gmath/test and
 lib/gpde/test Makefiles.

 missing from it, and TODO (pls help): only set OMPCFLAGS=-fopenmp for gcc
 >= 4.2.1


 seems to work very nicely indeed. race condition for lib/gpde mentioned in
 comment:4 still exists.
