Resolved in the CVS:

+#include <boost/mpl/aux_/config/msvc.hpp>
+#include <boost/mpl/aux_/config/workaround.hpp>
+
+// agurt 21/sep/04: portability macro for the sake of MSVC 6.x-7.0; 
+// resolves conflicts with 'boost::numeric_cast' function template.
+// use it in your own code _only_ if you care about compatibility with 
+// these outdated compilers!
+#if BOOST_WORKAROUND(BOOST_MSVC, <= 1300)
+#   define BOOST_MPL_AUX_NUMERIC_CAST numeric_cast_
+#else
+#   define BOOST_MPL_AUX_NUMERIC_CAST numeric_cast
+#endif

... only to find that it was masking an ICE. I'll have to look at it
later today.
