I'm trying to test a gfortran 4.6.0 patch that implements
REAL(16), which means that TFmode needs to be supported.
The GCC infrastructure currently does not build with TFmode
on FreeBSD, and so a patch has been created.  The last item
that needs attention is symbol versioning.  See the thread
starting at
