The variable optind must be reinitialized to 1 in order to skip over
argv[0] on FreeBSD. Because getopt() on FreeBSD will return -1 when
it meets an argument which doesn't start with '-'.
The variable optreset is provided on FreeBSD to indicate the additional
set of calls to getopt(). So, also reinitialize it to 1.
