I'm not sure what you mean by double-rounding bugs, though. It's not difficult to actually implement the HALFEVEN rounding behavior with bit twiddling.
Sure, as long as you've thought about it and done it carefully. The bit twiddling is easy to do, and easy to get wrong.
From the supplied patch it looks like you've done a good job, but there was no way to tell without it. I presume the listserv dropped it on the floor.
Andrew.
