Just FYI: arith-3.c still fails for me on pentium4. The sistem is fairly
unpatched Red Hat Linux release 8.0 (Psyche):

Linux moron 2.4.18-14 #1 Wed Sep 4 13:35:50 EDT 2002 i686 i686 i386 GNU/Linux

Compiler version: 4.1.0 20050310 (experimental) 
Platform: i686-pc-linux-gnu
libc-2.2.93.

Running target unix
FAIL: gcc.dg/cpp/arith-3.c  (test for bogus messages, line 257)
XPASS: gcc.dg/vect/vect-22.c scan-tree-dump-times vectorized 3 loops 1

However, testcase from description compiles and runs OK with "gcc -O2 pr20322.c".
