Bah.  It's part of C9X, and long, long existing practice.  Suppress it with
-ansi if you must, but it needs to be on by default.

On second thought, we shouldn't even suppress it with -ansi, since long
long support won't change the behavior of any conformant code.

Only because it's currently broken.  If we make it work properly, those who
don't care still won't care.

Who does, frankly, besides library writers?  People want a usable library,
not one which conforms to abstract ideals of beauty.

It is for the majority of users who don't build their own libstdc++.
