$ man -k hypot
hypot (3)            - Euclidean distance function
hypotf (3)           - Euclidean distance function
hypotl (3)           - Euclidean distance function
$ man  hypot | grep -C2 C99

       hypot():
           _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
           or cc -std=c99
