tin:~/src/gnu/gcctest>~/ia32_linux_gcc3_3/bin/g++ pr13351.cc -O -static
tin:~/src/gnu/gcctest>./a.out
Testing: 100000000 in 1.371 sec = 1.371 ns/per
tin:~/src/gnu/gcctest>~/ia32_linux_gcc3_2/bin/g++ pr13351.cc -O -static
tin:~/src/gnu/gcctest>./a.out
Testing: 100000000 in 1.381 sec = 1.381 ns/per
tin:~/src/gnu/gcctest>g++ pr13351.cc -O -static <-- 3.4 (20031125)
Testing: 100000000 in 1.447 sec = 1.447 ns/per
To me it looks faster (3.4 has regressed some what though).
