Though "getopt_long" points to an option in question in case of errors:

3) option doesn't allow an argument
4) option requires an argument

... by setting "optopt" variable, but leaves it's "longind" parameter untouched.
 This cause programmer either scan "longopts" array, or build one more
"switch(...)" to find the option in question.

So, "getopt_long" should be fixed to set "longind"
