Thanks, Vicente. I've done what I wanted (you can see the result in
libs/log/build/Jamfile.v2), although this took a whole day long and the
result is far more verbose than I'd like. My experience with Boost.Build is
really terrible so far.

But I'm facing a new problem. While it works as expected on Linux and
Windows with 64 bit MSVC, with 32 bit MSVC I get the following error:

E:/Sources/_SVN/boost-trunk/tools/build/v2/build\virtual-target.jam:1099:

The <address-model>32 <architecture>x86 <instruction-set>i686 properties
are added by my Jamfile, I suppose. The build succeeds if I explicitly
specify these properties in the bjam command line. I really have no idea
what is the problem here, please help.
