I certainly don't think I've ever tried it before, but it's really beyond my sphere of expertise. If you're building a shared libstdc++ that links against a static libm, I certainly don't think you want to be pulling the symbols from libm into your shared library (that would cause it to export symbols that should be in libm itself).
