// <math.h> is required to define generic macros signbit, isfinite and
// several other such functions.
//
// <cmath> is required to undef declarations of these macros in the global
// namespace and make equivalent functions available in namespace std. Our
// stlport implementation does this only for signbit, isfinite, isinf and
// isnan.
//
// NOTE: We don't write our test using std::signbit because we want to be
// sure that we're testing the bionic version of signbit. The C++ libraries
// are free to reimplement signbit or delegate to compiler builtins if they
// please.
