Close... The second use would also use the standard macros. Hence:
#if BOOST_WORKAROUND(BOOST_CXX_COMO, == BOOST_VERSION_NUMBER(?,?,?)) &&\
BOOST_WORKAROUND(BOOST_CXX_MSVC, == BOOST_VERSION_NUMBER(?,?,?))
In one of the previous discussions Dave mentioned that optimizing the
BOOST_WORKAROUND macro to be more terse. For example:
#if BOOST_WORKAROUND(BOOST_CXX_COMO,==,?,?,?) &&\
BOOST_WORKAROUND(BOOST_CXX_MSVC,==,?,?,?)
Or something like that :-) But that would be work to do after the core
config changes are done.
