Aha, fixed it!!

There is now a custom version of static_assert for CW-8.x:

// special version for CodeWarrior <= 8.x
#define BOOST_STATIC_ASSERT( B ) \
    BOOST_STATIC_CONSTANT(int, \
      BOOST_JOIN(boost_static_assert_test_, __LINE__) = \
        sizeof(::boost::STATIC_ASSERTION_FAILURE< (bool)( B ) >) )

Which, for example, translates to:

static const int boost_static_assert_test_10 = 
sizeof(::boost::STATIC_ASSERTION_FAILURE< (bool)( N < 2 ) >) ;

This forces the template instantiation on both function and non-function 
context. So for the first time all static_assert tests pass for this 
compiler :-) -- And this should also clear all the Spirit tests.

Enjoy.
