GNU libstdc++ prior to GCC 6.1.0, the overlay math.h always includes math.h from glibc, which defines isinf() and friends. GCC 6.1.0 includes a change (6c8ced3f4f867b72a623fe2f23efa204c5786a28) so that the overlay math.h never includes the glibc math.h when compiling c++. The overlay math.h sometimes includes "using std::isinf" Determined by inspecting libc math.h when building gcc.
