Because it is.  Nobody will be including, say, ropeimpl.h directly, they'll
include <rope>, which gets stl_config.h before ropeimpl.h.  How else would
the current thread #ifdefs work?

I don't.  Users can worry about it if they really want to.  Anyway, you
don't have to define it the same both ways; that just means you get two
copies of the STL code.
