I get the same (properly optimised) result
from both compilers:
gcc (GCC) 4.1.2 20060901 (prerelease) (Debian
4.1.1-13)
mips-linux-gnu-gcc (GCC) 4.1.2 20060901 (prerelease) (Debian
4.1.1-13)
I haven't tried a 3.4 crosscompiler, but the native one
also behaves
as expected:
gcc-3.4 (GCC) 3.4.6 (Debian
3.4.6-4)
