-----------------------------------------------------+----------------------
 Some of Boost source/header files trigger Clang's -Wimplicit-fallthrough
 warning, which finds unannotated fall-throughs between case labels in
 switch statements (more details on the diagnostic here:
 http://clang.llvm.org/docs/LanguageExtensions.html#the-clang-fallthrough-

 attribute).

 I propose introducing BOOST_FALLTHROUGH macro to be used to annotate non-
 trivial fall-through between case labels.

 A patch with the macro and fixes to the code is attached.
