--- Comment #5 from cqwrteur <unlvsur at live dot com> --- actually a lot of dlls are not copied correctly. libstdc++-6.dll libatomic.dll libquadmath.dll libssp.dll are all copied with 32 bit dlls. And libgcc_seh.dll is not copied. I think the copy to bin behavior should be removed. It should be just like normal linux distribution. 64 bit dlls in lib. 32 bit dlls in lib32.
