The latest gcc2 on the ftp.gnu.org site is gcc 2.95.3. There is officially no such thing as "gcc 2.95.4". Probably you are talking about a patched version of some gcc2 cvs snapshot - that's what distros provide. Please specify exactly what gcc version you are talking about. And there _is_ problem with gcc-2.95.3-compiled kernel: latest cvs glibc testsuite segfaults in nptl tests. There are no failures with the kernel identically configured, but compiled with gcc 3.3.4 or 3.4.1. So gcc 2.95.3 as supplied by gnu.org miscompiles the kernel (futexes?). Either fix the kernel or drop gcc2 support. -- Alexander E.
