This is interesting information, but perhaps there should be another flag (heh)
that turns off this compiler flag modification, for those that really want
to do it.

I can see how stability is important and expected, especially in glibc,
and this "how to get a stable build at all costs" info is important, and not
to be lost.  But it would be nice to have the Gentoo cake and eat it too, :-)
turning off this safety net when one really wants to experiment and perhaps
help flush out the bugs that make this net necessary in the first place.

Is there a way to do this easily and I just don't know it?

Thanks,
