I'm not asking greg to reject the patch nor dictating Mark Mauler change it. Since greg is willing to accept a patch to "fix" it, I'm willing to provide the patch in this case. I think that's fairly normal way to clean things up. > I see nothing wrong with that if statement. It's perfectly valid, > idiomatic C.

"someone" includes me. :) > (I would look askance at something that did an assignment as one of > the parameters of a procedure call in an if statement, though.) *nod* thanks, grant
