The XFree86 servers still don't run with a kernel compiled with a gcc 2.8.x
with the following command line:

-march=pentium -O3 -fomit-frame-pointer <the usual align stuff>

It seems that the i586+ optimizations break the linux Unix sockets code. The X
server dies with "cannot open socket" message. At first I thought it's a
problem with the X servers, but when I reported it I received a response that
gcc 2.8.x breaks X only on Linux.
Just a while ago I have compiled the 2.0.34-pre3 kernel with gcc 2.8.1 and
-m386 instead of -march=pentium and with -O2 -fomit... -fno-strength.. - the
effect is the same, X won't run.
