Hi,
I have just push the glibc-2.10(.1) toolchain rebuild into [testing].
Apart from the glibc bump, I also updated gmp and took a newer gcc-4.4
snapshot which fixes a few compile issues.
Here goes some information about the glibc update:

The whole broken DNS server issue rears its head again. It is a bit
more fixed than with glibc-2.9, but if you are having issues, read the
above link for ways to handle this.
Some C++ programs that did incorrect things with string const-ness will
fail to compile with glibc-2.10. If you have issues, look to Fedora for
patches as F11 has done their builds with this.
