	Trust us.  They are matched pairs.  They *may* work when they
	are not matched but there are definitely combinations where you
	don't want to try it.

	e.g.
		mismatched version have been known to result in named-xfer
	trying to close all 2 billion file descriptors before doing anything
	else.  This takes significant time:-)

	On top of this the arguement list has expanded over the years and
	those new arguements get used.
