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,
João
