ustrnicmp - Compares up to n letters of two strings ignoring case. Allegro game programming library.

       This function compares up to `n' characters of `s1' and `s2', ignoring case. Example:

          if (ustrnicmp(prefix, long_string, ustrlen(prefix)) == 0) {
             /* long_string starts with prefix (ignoring case) */
          }

       Returns  zero if the strings are equal, a positive number if `s1' comes after `s2' in the ASCII collating
       sequence, else a negative number.
