More to add on the gcc 2.96 problems. After compiling a Linux 2.4.1
kernel on gcc 2.91, running SCI benchmarks, then compiling on RedHat
7.1 (Fischer) with gcc 2.96, the 2.96 build DROPPED 30% in throughput
from the gcc 2.91 compiled version on the identical SAME 2.4.1
source tree.

I think RedHat should jetison gcc 2.96 as soon as possible...

Tests run on a PIII system limited to 90 MB/S PCI throughput.

gcc 2.91 on a PIII system in sci_copy mode 85 MB/S
gcc 2.96 in RedHat 7.1 (Fischer) in sci_copy mode 63 MB/S
