Its probably appropriate to drop gcc 2.x support at that point too since
it's the major cause of remaining problems
What problems does it cause? 2.95.4 still seems to work fine for me.
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.
