Log: Add isnan() and isinf() to the global namespace in libstdc++'s <cmath>. The standard (n3242, section 17.6.1.1, paragraph 4) says that, because these are declared as macros in the C specification (even though they are implemented as functions in the C++ library) they should be in the global namespace. A surprising number of configure checks rely on this. It was broken by recent cleanups to math.h.
