Sorry, lost track of this conversation in the end-of-month mail archive rollover... Uh, to be honest, I guess I don't really have a rational reason for wanting to switch to -Wnarrowing first; it's really more of an emotional/aesthetic desire I have on my part... Feel free to do the switch in the other order if that turns out to be easier. Anyways, from the rest of the discussion, it looks like this will be waiting for GCC 11 anyways, so I'm already getting my "hold off 1 release" wish, so I guess I don't really care as much about the -Wnarrowing part as much any longer...
