Incidentally, just yesterday I finally ported to bjam+BBv2 a shell 
script I've been using for the same purpose. See attached. You should 
put headers.jam file in the same directory as your Jamfile[.v2] or 
somewhere where Boost.Build can find it (e.g., in BOOST_BUILD_PATH).

For example, to test the compilation of Boost.Spirit headers, in 
(boost-root)/libs/spirit/test/Jamfile.v2 one could have:

     import headers ;
     import testing ;

     test-suite "spirit.headers"
         : [ headers ../../../boost/spirit ]
         ;

At this point the code is the documentation, but I added some comments 
explaining each function's purpose.

Perhaps this, or something along the lines of it, could be added to the 
regression tests, to ensure that all headers compile independently. 
FWIW, my former bash script used to report lots of non-compilable files 
inside boost.

What do others think about this? I'd like to hear your comments on the 
approach and implementation, as well as bug reports ;-)

Best regards,
