Subject: [PATCH] Updated Boost Build's doxygen.jam toolset module to not rely
 on Boost Build leaving behind a dangling 'current project' reference after it
 finishes loading all of its project modules.  This should fix Boost library
 documentation build failures encountered after revision [79874].
