Hi, the current set of gcc in sid/i386 is OK (-march=i486 -mtune=i686). gcc-3.3 3.3.6-12 gcc-3.4 3.4.5-2 gcc-4.0 4.0.2-7 Only experimental gcc-4.1 4.1-0exp6 have to re-enable cpu-default-i486.dpatch On the other hand, the (now tested) results for gcc -m32 on amd64 are a little bit different: gcc-3.3 -march=i386 -mtune=i386 gcc-3.4 -march=i386 -mtune=i386 (for 3.4.5-1) gcc-4.0 -march=i486 -mtune=i486 Petr
