       comparison functions were, in turn, derived from GNU Diff 2.7.

       The  strcoll()  function compares the two strings sting1 and string2.  The comparison is based on strings
       interpreted as appropriate for the program's current locale for category LC_CTYPE.

       fstrcoll - fuzzy comparison of two strings using the current locale

       The fstrcoll function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL.  A value  of  0.0
       means the strings are utterly un-alike.  A value of FSTRCMP_IDENTICAL means the strings are identical.  A
       value  of  more  than  FSTRCMP_THRESHOLD  (it lies between 0.0 and FSTRCMP_IDENTICAL) would be considered
       "similar" by most people.

       A value of FSTRCMP_ERROR (always negative) indicates a malloc(3) or mbstowcs(3) failure.
