it seems like it doesnt have any gcc patches what is present in fedora/debian for latest glibc/gcc pity, o unable test it with gcc4. waiting for clearing
I'm not going to add port gcc4 patches from head to this release. Upstream promises glibc-2.3.6 will be released to coincide with gcc4 and will contain all the relevant pathces. If youu want to build glibc with gcc4, I suggest you work with glibc's HEAD.
