Yes, there is code to inhibit that warning (when it's the expected
number of shift/reduce conflicts), but there's some ordering subtlety
that I've never taken the time to figure out.  That is, when saying
"make -jX", files are sometimes compiled in an order that makes the
warning appear, and sometimes not.

If somebody could figure out what's making this unstable, that'd be
appreciated.
