Hi,

Several libraries use 'glob' to find the headers for doxygen, and some
of them search from boost root. This doesn't find anything unless 'b2
headers' is run first, which causes the build to fail (the doxygen
rule requires at least one source). Is there a way to make sure the
'headers' target is run from $BOOST_ROOT/doc/Jamfile.v2 before the
globs in dependent jamfiles are evaluated? Of course the globs could
be used against local header files, but it'd be nice if we didn't have
to require that, e.g. if a module wants to include a header from
another module for some reason.

thanks,

Daniel
