Comment (by Kim Barrett <kab_at_[hidden]>):

 I've added an example program for use in comparing the performance with
 and without the patch. With gcc4.1 about 25% of the unpatched time is
 spent in the cross-cast. I don't have access to a gcc3.x system at the
 moment to measure there, but expect the results on such a platform to be
 *much* worse. I'll be interested to hear what the difference is on a
 Windows platform.
