[Bug tree-optimization/39207] [4.4 Regression] Strict aliasing warnings in libstdc++ headers

[mmitchel at gcc dot gnu dot org]

The key question is whether the bogus warning could indicate a potential for
miscompilation.  If it's "just" a bogus warning, then it's going to annoy and
confuse people, but not result in too much damage.  But, if this means that
we're likely to miscompile things, then we have a worse problem.  Of course,
until someone demonstrates an actual miscompilation, that's perhaps something
of a theoretical problem.

I'll leave this as P3 until we know more.
