   Hi.

>    I'll look into it now and let you know how it goes...

   I think I've resolved the issue in revision [79887].

   http://svn.boost.org/trac/boost/changeset/79887

   Daniel, could you test on your end and see if this resolves your 
issues? Hopefully without introducing any new ones. :-)

   I'll commit a few more cleanup patches I have lined up, but this 
should be a minimal fix for the problem at hand.

   The issue was that the boostbook toolset wants to generate some sort 
of a global xml catalog file (whatever that is :-)) needed when 
generating its boostbook targets. This catalog file does not seem to 
change between different invocations and so the toolset wants to reuse 
it instead of generating a new one for every boostbook 
target/property-set/project. To achieve this it created the the 
xml-catalog's virtual-target and had it registered to the 'root boost 
build project'. To reach this 'root project' it used a dirty trick 
relying on Boost Build leaving its 'currently loaded project' reference 
dangling even after done with loading all of its project modules. Now I 
changed it to not use the root project at all but to simply use the 
first project requesting this file instead.

   Ideally this target would get registered to the central 'boostbook' 
project but that is a standalone project without a 'location folder', 
i.e. it can not create new targets but only reference preexisting ones. 
This is something that can be changed if Boost Build is updated to allow 
creating new targets from stand-alone projects, but the current solution 
seems clean enough for me.

   Hope this helps.

   Best regards,
