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
