FreeBSD 5.0 is scheduled for a 15 Dec 02 release. We have
24 days to find the problems. With the recent spat of
problems reported after DP2 was released, I suspect 15 Dec
02 is optimistic.

You know the reason why 3.2 pre-release was brought into
the tree, right? GCC has changed the C++ ABI between
3.1.1 and 3.2. If FreeBSD 5.0 shipped with 2.95.3, then
5.x would use 2.95.3 until 6.0 was released. Try getting
support from the GCC folks for 2.95.3.
I respect David's judgement about bringing 3.2.1 into the
tree, but your statement above ("totally blown out...")
suggests you don't follow GCC development. Several
significant bugs were fixed between our pre-release version
and 3.2.1.
