Comment:

 Well, this is the way of doing it automatically!  Or at least the best we
 can achieve with current the Boost.Build :-(

 An alternative would be to add a <build>no property to the
 has_long_double.cpp compile test for platforms which are known to have no
 long double support.  Then you wouldn't see the failure, but you would
 still see a lot of targets skipped - rightly so IMO since part of the
 library can't be built there should be at least some user warning?

 Would this be acceptable, and is there a way to detect the debian version
 within Boost.Build?

 Thanks, John.
