[UDUNITS #QVW-190351]: ut_get_converter and constness of args.

That surprises me because, as I said, the ut_get_converter() function might 
modify the passed-in units.

Probably indicates a bug in gcc 4.3.2.

Sorry, I'm afraid I can't simultaneously help you *and* keep my contract with 
the C programming language.
