Thanks :-) But it's not the coding of what's described in the wiki that
is laborious. It's the translation of all the Boost.Config code to use
the new macros.

Well others will want to comment on their expectations. The tipping
point for me in the direction I suggest is that I found many instances
in current Boost code where there was only reference to _MSC_VER, with
the expectation that it would apply in both real and simulated modes. SO
it's not translating the use of BOOST_MSVC that worries me, it's the
translation of all the _MSC_VER uses. Should they be converted to
