bison 1.875 and later as we did from earlier bison releases. Eventually we will probably want to adopt the newer message spelling ... but not yet. Per recent discussion on pgpatches. Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql grammars, since these do not affect regression test results.
