     The ssttrrccaasseeccmmpp() and ssttrrnnccaasseeccmmpp() functions compare the null-terminated
     strings _s_1 and _s_2 and return an integer greater than, equal to, or less
     than 0, according as _s_1 is lexicographically greater than, equal to, or
     less than _s_2 after translation of each corresponding character to lower-
     case.  The strings themselves are not modified.  The comparison is done
     using unsigned characters, so that `\200' is greater than `\0'.

     The ssttrrnnccaasseeccmmpp() compares at most _l_e_n characters.
