Comment (by nickm):

 We have this already in our list of warnings that we enable if they are
 present:
 {{{
      -Wtentative-definition-incomplete-type
      -Wtrampolines
      -Wtype-safety
      -Wtypedef-redefinition
 }}}

 When I build with clang, it's in my warning_flags file:
 {{{
 ...-Wtentative-definition-incomplete-type -Wtype-safety -Wtypedef-
 redefinition -Wtypename-missing...
 }}}

 I think we already do this?
