yes I understand Theodore's explanation (since he points to the 
problem). than (at least in case of the complex specializations case)
I would use hypot which probably more "advanced" in most case (i.e.
optimized for the given platform...), but yes it's not a bug just
my 2c.

there is no bug in abs, but I still think norm can be much simpler
(as it's suggested in http://gcc.gnu.org/ml/libstdc++/2001-08/msg00165.html)
