hi, I am not sure how do deal with unwanted cflags(cxxflags), so I ask here :)
For kjs for example -ffast-math is known to cause problems, as we stricly rely on IEEE compatible floating point, NaN, Inf, signed Zero and all the stuff. So the question should I filter them? or leave it to the user to optimize(break) his system? If you say yes to filter, it also involves -fno-math-errno -funsafe-math-optimizations -ffinite-math-only -fno-rounding-math -fno-signaling-nans -fcx-limited-range and I have no clue if there are msvc (or other compiler) versions of them. If you are against filter, how should I deal with bugreport caused by XYZ cflag?
