Comment (by johnmaddock):

 >For the second part, are you saying this will require a separate ticket
 and patch for each library that's updated to use the annotation?

 That would certainly increase the chance of acceptance.

 One thing about your patches though: some compilers (GCC?) will warn if
 there are empty statements - which is exactly what your warning patch will
 generate on non-clang compilers.

 So BOOST_FALLTHROUGH needs to be defined to be used without a following
 ";".
