BOOST_NO_VARIADIC_TEMPLATES is not defined. The signal0, signal1, etc classes are not available when using the variadic implementations, I plan to mark them as deprecated. Also the arg1_type, arg2_type member typedefs are not available and are replaced with a "arg" member template class. Documentation updates to follow. [SVN r53355]
