I am looking at the trunk version of has_xxx.hpp.
The macros BOOST_MPL_HAS_MEMBER_TEMPLATE_SUBSTITUTE_PARAMETER and BOOST_MPL_HAS_MEMBER_TEMPLATE_ACCESS appear to be not defined anywhere.
This is OK for the first because it is actually not used anywhere to generate code, although it is being passed around to other macros. If it serves no purpose, perhaps it should be removed as it then only serves to obfuscate the code, unless of course there are future plans to define it.
The second, however, is being used to generate code in one instance dependent on some version of a compiler, so it needs to be defined somewhere or else an error will occur.
Please check this out if this is going into 1.44.
My apologies. This is a false alarm as the macro which eventually uses BOOST_MPL_HAS_MEMBER_TEMPLATE_ACCESS can never be called.
