#     
#     Pull fallthrough fixes from Gustavo Silva:
#      "This fixes many fall-through warnings when building with Clang and
#       -Wimplicit-fallthrough, and also enables -Wimplicit-fallthrough for
#       Clang, globally.
#     
#       It's also important to notice that since we have adopted the use of
#       the pseudo-keyword macro fallthrough, we also want to avoid having
#       more /* fall through */ comments being introduced. Contrary to GCC,
#       Clang doesn't recognize any comments as implicit fall-through markings
#       when the -Wimplicit-fallthrough option is enabled.
#     
#       So, in order to avoid having more comments being introduced, we use
#       the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang,
#       will cause a warning in case a code comment is intended to be used as
#       a fall-through marking. The patch for Makefile also enforces this.
#     
#       We had almost 4,000 of these issues for Clang in the beginning, and
#       there might be a couple more out there when building some
#       architectures with certain configurations. However, with the recent
#       fixes I think we are in good shape and it is now possible to enable
#       the warning for Clang"
