Matthias, I'm not sure. I know I was told that hppa was okay. Also from my conversations with Jakub it appears i386, ia-64, alpha and sparc32 should be fine. So I would suggest we focus on checking the status of arm, hurd-i386, m68k, mips, mipsel, s390 and sh. I'm not sure how many of those arches have even had glibc 2.3.1 built on them. Jack
