       double fmax(double x, double y);
       float fmaxf(float x, float y);
       long double fmaxl(long double x, long double y);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fmax(), fmaxf(), fmaxl():
           _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
