The source builder is new for us, but we still managed to get the nios2 binutils, gcc compiler, and newlib to build yesterday and we are pleased with that. We had to move the newlib version back and patch it for nios2 because our corporate firewall blocks all cvs pserver traffic (including client initiated).
Chris and I have discussed whether it made sense to ask for periodic
CVS snapshots (monthly?) so we wouldn't be hammering their CVS
server and it avoids firewall issues.

FWIW gcc itself is apparently missing a check for the development side of
zlib. It will just fail somewhere in the LTO link as I recall. But I
haven't run
that down either.
