While trying to pinpoint an *intermitent* warning/error with g++ 4.3 "mf/unit.h:84: error: no integral type can represent all of the enumerator values for `metafloat::core::helpers::details::aligner<7u, metafloat::core::float_t<0l, 0l, 0ul, CAT_NRM> >::<anonymous enum>'" i finally got it to ice with the attached version. Even better, the venerable g++ 3.4 as shipped by Cygwin also craps out.
