Update to 1.4c

Chagelog:
Version 1.4c

- updated option string up to OpenSSH 5.6
- when using -f, set gate_time to 0; the assumption is that
  it is being used for infrastructure (i.e. in a system startup),
  has been tested, and bombing out just because the remote end is
  not up is not the desired behaviour.
- add patch from Thorsten Glazer for configure, fixes misplaced
  parenthesis and check for __progname.
