I think my problem (re: type-punning) is triggered by the fact that
-fast turns on strict aliasing rules. I'm puzzled though because it's
flagging my classes as being problematic. And I can't see why that is.
Sure I could just turn off -fast, or at least strict aliasing, and
probably continue on my way....but stuff like this just gets under my
skin because something is obviously not right! Better to fix it now
then have it haunt you later on.

-fast is obviously doing something drastic other than just flipping

"fast" is a sure sign that it's doing something weird.
I have a couple guesses but I'm not a compiler expert so hopefully
somebody who is on this list can tell me why I have problems (with
ppc_intrinsics.h being gone). This could be the root of your problem,
also, but you might want to check out the docs on -fast because it
gives a list of all the flags it turns on. You could put in all the
flags by hand and then slowly turn them off until you found the one
that was causing the errors to appear.
Note: I tried this myself, it seems to be -fast itself that's
responsable for my problems.
Any engineer want to comment? Pretty easy to recreate :)
