I can't reproduce this, but ISTR something similar when the parser was
built with byacc. I think a sufficiently modern version of bison should
work. Make sure you delete builtins/evalstring.o and
builtins/libbuiltins.a after rebuilding y.tab.[ch]. The dependency there
is tricky, and it's best just to do it explicitly.
