    Add a fallthrough macro. · 6c3c9435

    This macro defers to __attribute__((fallthrough)) on GCC (and
    clang).  Previously we had been using GCC's magic /* fallthrough */
    comments, but clang very sensibly doesn't accept those.
    Since not all compiler recognize it, we only define it when our
    configure script detects that it works.
    Part of a fix for 34078.
