bison 3.0 released

Well, nobody said being a developer is always easy. In LilyPond, we tend to have one new GCC C++ code generation bug turning up per year. And we are talking about the version of GCC shipping with Ubuntu here (or in one case, Fedora). I think our last Fedora code generation bug was bad enough that it was among the reasons for postponing Fedora's release.

So you can of course ask "why would it be the job of a music typesetting programming team to track down code generation problems in a compiler?". But then somebody needs to do it...

Moving to newer Bison would not be really feasible right now. But at one point of time, we certainly will do so. The LilyPond grammar does a lot of weird things, like generating artificial tokens and hoping that the grammar state has not permanently registered the previously seen token already. GLR parsers might or might not make this easier.
