[Discuss-gnuradio] Patch for OptionParser backwards compatibility

From: Michael Dickens
Subject: [Discuss-gnuradio] Patch for OptionParser backwards compatibility
Date: Tue, 28 Aug 2007 14:58:40 -0400

Someone recently added a "--which" option to the usrp_fft example, that works correctly with the OptionParser provided in Python 2.4 or newer. But for those using that provided with Python 2.3, it doesn't work. Simple fix; here's the patch. - MLD
