OK third answer, I think this is fine I have that in my cflags both on x86 and
ppc. There are a variety of programs out there that just don't take aliasing
seriously (or even now about it) so it is not a bad work-around. strict
aliasing is usually triggered with various optimization.
So I think we will adopt it, at least on amd64 and probably ppc (although
I have a feeling most ppc gentooist already have it in their cflags as it is a
known offender in ppc-land).
