Ok, new conglomerate patch is posted; includes a few more return conversions (particularly in msvcrt) and a few other minor changes compared to the previous conglomerate.  I would call this one a commit candidate, pending your review.  I don't plan to commit this one, though; I want to switch each of them to some manner of buffered output first, but I figured this form would be easier to review.  I'll post the buffered patch as soon as it's ready, you can review whichever one you actually prefer :)
