Thanks.  You're right, that's quite relevant.

I suppose another question that's implicit but that I didn't ask is: 
would it be a desirable feature to give users a way of getting a fully 
conforming C++ language/library implementation without having to 
reconfigure and reinstall?  Should there be a compiler switch that does 
that?

Please note that this is not a rhetorical question.  I'm not pushing 
for one answer or the other.  (It's also a question that's not 
tremendously relevant right now, since it's a little late in the gcc 
release cycle to add a new feature like that.)
