sheer laziness and luck made it a 'works for me' item. But I accept its probably
stupid, and I'm going to try and adopt a cleaner path such as the recipe given

And you assert this is known to work, right now, from a pre-gcc-3 state to a
gcc-3 state? (I'm not in that state now, I made my shift.) I think there is
enough traffic here to suggest we missed a rather important line or two in
UPDATING along the lines of:

	"its not exactly a flag-day, but please be careful if you want to cut to
	 gcc 3.3 right now. Here is a known working recipe, and what you should

mind you, the same can be said of the pthreads instability, and a few other
recent earthquakes.  We don't seem to get quite as many Subject: HEADS UP as we
used to.

I think that would be a really nice idea. But, I think you probably want to
clear the 103 other tasks ahead in the queue :-)

Thanks to everyone for the tips on upgrading to 3.3 btw. Nice to be here.
