  I'm not certain yet which commit in the last couple of days caused this,
but the current llvm/dragonegg svn shows a major improvement in the runtime
of the xplor-nih testsuite when xplor-nih is built with FSF gcc 4.6.1 and the
dragonegg plugin at -O3 -ffast-math -funroll-loops. Previously the xplor-nih
testsuite always executed in ~40 sec but now it is coming it at 34.5 sec which
is about the same result seen for xplor-nih built with  native FSF gcc 4.6.1.
It will be interesting to find out if the Polyhedron 2005 benchmarks shows this
behavior as well. Nice.
