--- Comment #25 from Florian Weimer <fweimer at redhat dot com> --- (In reply to Matthew Woehlke from comment #22) > case B: > ... > [[gcc:fallthrough]] // suppress warning for fall-through to 'case C' Do we have such attributes in the C compiler? I contemplated using any comment whatsoever as an indicator that fall-through is expected. In the end, need general (syntax-based) unreachable-code detection, so that return statements and no-return functions suppress the warning as well, and so on. At least if this will be part of -Wall.
