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

       The fstrcmp() function compares the two strings, string1 and string2.

       fstrcmp - fuzzy comparison of two strings

       The  fstrcmp  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) failure.
