I was just following the precedence in boost/config/stdlib/libstdcpp3.hpp:

#if defined(__GLIBCXX__) || (defined(__GLIBCPP__) && __GLIBCPP__>=20020514) // GCC >= 3.1.0

This is what's currently in the boost svn.
With trial-and-error I found out that __GLIBCPP__ is not defined by
the "experimental" g++ 4.3.0 from the gcc svn trunk.

I don't know what's the best set of #ifdefs in the long run. I'd leave
that to people more knowledgeable about the future g++ development path
(e.g. Doug).
