[boost] [test, parameter, fusion] en/disable_if name clash in trunk

it seems that the new boost::unit_test::decorator::enable_if, introduced in [1] clashes with boost::enable_if under certain circumstances. this currently breaks the boost.heap testsuite (see [2]). maybe the test/parameter/fusion maintainers could discuss, how that can be resolved? thanks, tim [1] https://svn.boost.org/trac/boost/changeset/74663 [2] http://www.boost.org/development/tests/trunk/developer/heap.html
