  Has -funsafe-math-optimizations picked up any new components
in gcc 4.6? I am finding that cns_solve crashes when built with...

-fno-sign-zero -O2 -funsafe-math-optimizations

..but not with...

-fno-sign-zero -O2 -fno-signed-zeros -fno-trapping-math -fassociative-math -freciprocal-math

which would suggest that some new components to -funsafe-math-optimizations
have been added but not documented yet.
