No. I've been developing on RH4.2 (making source builds on that), and trying to
use rpms for RH5.0 built at RedHat to verify the glibc2 performance. May have to
do  a build from source to get to the bottom of things, but I'm hoping not...

Well, have you tried the CVSup static package on RH5.0 yet? Don't know if it
would work, but if it did it would allow you to get snapshots as you want; in
fact I'm doing that right now trying to track down a problem introduced sometime
after 980112 and before 980201. Downloading 980120 right now as I (sort of)
binary search through the possibilities.
