[boost] Trunk Boost Jam version users need to recompile.

5 May 2008

      Hi all.

   Just a heads up that anyone using the trunk version of Boost Build 
newer than revision 45158 and the trunk version of Boost Jam (version 
3.1.17) older than that revision needs to recompile their Boost Jam.

   Note that this does not affect people using the current release 
version (3.1.16) as the new Boost Build code preserves old behavior for 
older versions. This includes testers since they use the release version 
of Boost Jam.

   Without this recompile the thing that can happen is that some paths 
get parsed incorrectly.

   Best regards,
