I'd think that if we hit the decltype case, we no longer need to enter the 
compiler-specific branches below that. So

#if !defined(BOOST_NO_CXX11_DECLTYPE) && 
!defined(BOOST_NO_CXX11_TEMPLATE_ALIASES) && 
!defined(BOOST_TYPEOF_EMULATION)
#   define BOOST_TYPEOF_DECLTYPE
#   if !defined(BOOST_TYPEOF_NATIVE)
#       define BOOST_TYPEOF_NATIVE
#   endif

#elif defined(__COMO__)

perhaps? Tested as before.
