[Boost-users] [Parameter] Warnings from Preprocessor

I recently updated to 1.63 from 1.57, and I'm now getting warnings from usages of BOOST_PARAMETER_MEMBER_FUNCTION on Windows (msvc-12.0) like: warning C4003: not enough actual parameters for macro 'BOOST_PP_SEQ_DETAIL_EMPTY_SIZE' warning C4003: not enough actual parameters for macro 'BOOST_PP_SEQ_DETAIL_IS_NOT_EMPTY' The code appears to be working, but since it's used in headers, I get a lot of warnings. Here's one of the usages: BOOST_PARAMETER_MEMBER_FUNCTION((Revision_t), CreateForegroundWhite, tag, (optional (imgclass, (Class_t), ClassPrint) (fromimage, (bool), true) (blackasgray, (bool), false) )) Should I be concerned about the warnings? Any way to get rid of them? Thanks, Phillip
