Ralf, I tweaked my own local copy of the 'factory.hpp' file to use
file-iteration just for this part:

BOOST_PP_REPEAT_2ND(
    BOOST_PP_DEC(BOOST_MPL_LIST_PARAMETERS_NUMBER)
    , BOOST_MPL_AUX_LIST_FACTORY_SPEC
    , unused
)

Preprocessing <boost/mpl/type_list.hpp> (which includes 'factory.hpp') took me
7-8 minutes before.  It now takes 6 seconds--I'd say that is an improvement.
