Looks like a "feature" to me. Apparently some important system header does
sizeof(incomplete).

Odd, since the Intel-specific BOOST_STATIC_ASSERT is

#elif defined(BOOST_INTEL_CXX_VERSION)
// agurt 15/sep/02: a special care is needed to force Intel C++ issue an
error
// instead of warning in case of failure
# define BOOST_STATIC_ASSERT( B ) \
    typedef char BOOST_JOIN(boost_static_assert_typedef_, __LINE__) \
        [ ::boost::STATIC_ASSERTION_FAILURE< (bool)( B ) >::value ]

which looks pretty close to what checked_delete uses.

Dependencies. I hate dependencies.
