I very much agree with Dietmar that this is an important issue for
boost.org.  I don't know of any single general approach to dealing
with implementation variations.  It seems to me there are several
approaches, none perfect, but each useful at least some of the time:

   *  A single general "pretty good" implementation.
   *  (Gasp!) Macros.
   *  Separate implementations; install only your favorite.
   *  Template specialization, traits, and related techniques.
   *  Others?

I am writing a policy paper trying to identify when it is appropriate
or not appropriate to use each of these techniques.
