Sorry, I forgot to phrase my post in the form of a question...

Is this what you're supposed to do?  Or am I misunderstanding how this 
whole file works?  Those implicit definition warnings aren't really a 
good sign (in general), so I'm not sure if this is what is supposed to 
happen.

Also, is this the correct way to take care of the mis-configuration?  It 
works ok for libstdc++-v3, but if I try to compile libfortran stuff gets 
*really* screwed up.
