Exceptionally, I think we can ho ahead with this one too... *BUT* please 
double check that you are not unconditionally using C99 functions, 
that's a very effective way to break the build on less widespread 
targets. For example I see a std::copysign which needs a replacement 
conditional on _GLIBCXX_USE_C99_MATH_TR1
