I need to tidy up a bit and add the appropriate documentation for the 
Wiki but here is the utcome of running the Polyhedron 2005 Testsuite 
using the harness that is supplied with the suite.  There are clearly 
indicators where work is needed for gfortran but..... see for yourselves!

The version of gfortran is patched with the inline dot-product and the 
improved dependency.c as described on the lists. I will unpatch and redo 
the test (needs all night!)
