  Hi,

  To take care of dependencies in my project using boost, I used to
invoke gcc with the option -MM. However, since using boost 1.47, this
does not work anymore. The precompiler aborts with the message:

/usr/local/include/boost-1_47/boost/signals2/signal_type.hpp:29:2:
error: #error This header requires BOOST_PARAMETER_MAX_ARITY to be
defined as 7 or greater prior to including Boost.Parameter headers

  Because the macro BOOST_PARAMETER_MAX_ARITY plays no role whatsover
in this invocation of gcc, I think that boost should solve their
internal problem with the "arity" in some other way.

  In the mean time I define the macro in my make rules to generate the
dependencies, but there it is obviously misplaced (any tips or tricks
are welcome here).

  All the best,

Ytsen.
