Well, since the actions are written in the target language, and bison
supports multiple languages, it makes sense to have a %language
directive, imho.
Ideally skeletons should be required to declare their language, so that
using "--skeleton lalr1.cc" or "--skeleton my-erlang-parser.skeleton" on
a grammar with "%language java" would produce a bison-time
warning/error.
