Perhaps -traditional should disable -fstrict-aliasing. However, I think
-traditional is a fairly useless option (which is e.g. not usable with
glibc); does anyone actually find that they still have old C code which
works with -traditional and not without and which they need to be able to
recompile with new GCC versions but don't want to convert to standard C?
