Provided that we find a version of yacc that doesn't choke on the
grammar files. Also, we got an uncertain road ahead for Valas before
0.35.1, and then vala 0.39.6 did a dirty bump in which they rely on a
practically unreleased version.
So yes, the archeological approach could work, but I wouldn't
necessarily count on it being "easy".
