 compilation of boost.log (http://boost-log.sourceforge.net) within boost
 1.41 on Mac OSX 10.5 and gcc 4.2.1 fails due to an "external linkage"
 error:

 I had reported the problem to the boost.log maintaner before to open the
 ticket and the response was:


 {{{
 Looks like a compiler bug to me since the
 derivation_value_traits::to_value_ptr clearly has external linkage.

 You should report the problem to Boost.Intrusive maintainer.
 I'm not sure I can work it around on Boost.Log side.
