That was part of a series of changes to eliminate all warnings in build
under clang (gcc still issues some warnings). I didn't notice at the
time that we were using an extension in a nominally yacc-compatible grammar.
Aside from the options you listed, we could check the bison output into
the tree like we do with lib/krb5/krb/x-deltat.y. But we might just
revert the commit and live with the warning. That warning shouldn't
cause an error in a -Werror build since it isn't coming from the compiler.
