#     Makefile: Enable -Wimplicit-fallthrough for Clang
#     
#     With the recent fixes for fallthrough warnings, it is now possible to
#     enable -Wimplicit-fallthrough for Clang.
#     
#     It's important to mention 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. Notice that 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 have to 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.
