Is there any way to make gcc or clang warn about missing breaks in switch statements?

Specifically, I almost always want case statements to end with breaks, and it would be great it I could get the compiler to complain if I don't. Even better would be if it would look for either a break statement or a "// fall through" comment.

Is there a different solution people use to help themselves not screw this up?

gcc coding-style switch-statement clang gcc-warning
