I have successfully built the Debian glibc package now on s390. I am testing it in a chroot on top of Debian unstable running several builds, fine so far. I have been told that s390 doesn't need a libgcc compat patch, so that should be clean as well. I have generated new ulps for the math tests and will forward them to upstream. This means glibc 2.2.92 looks rather complete on s390. Gerhard
