Yes.  -stable doesn't automatically generate a rule to construct y.tab.h,
and because of this the build doesn't actually work in some cases:
- when someone removes y.tab.h.
  Workaround: don't remove it.
- when the command that builds y.tab.h as a side effect doesn't happen to
  get run before y.tab.h is used.
  Workaround 1: always build .depend first.
  Workaround 2: order SRCS magically so that the command gets that builds
  y.tab.h gets run early enough.
  Workaround 3: don't use -j, or workaround 2 might not work.
