Thumbs up or thumbs down: stl_config.h ?

yes! please do this. You can take the _GNU_ bits and add them to 
inclue/bits/c++config.h to start with, and substitue c++config.h insted 
of stl_config

eventually we want to remove the uncesessary code from the STL itself. I 
think Matt is doing this anyway, so I don't want to duplicate efforts.

Matt?
