Some compilers would accept 0-sized arrays. Some others accept -1-sized

By the way, in the end I settled on:

#define STATIC_ASSERT_MSG(b, msg) \
    { \
        struct msg \
        { \
            msg(::boost::loki::int2type<true>) {} \
        } msg((::boost::loki::int2type<(b) != 0>())); \

which works like a charm. The way things seem to be, though, it looks like
nobody would be interested in adding something like that to boost.
