SSE2 has come of age in most legislations :-) So has amd64. The only reason to run i386 is on machines that don't support amd64, e.g. old Soekris [45]xxx and the like. Note that flac has assembly optimizations for various SSE levels that are properly enabled at runtime based on CPUID. You're getting all that on modern CPUs. -- Christian "naddy" Weisgerber naddy@mips.inka.de
