Comment 109 for bug 908508

I would suggest making the minimal change that actually works and doesn't make things more confusing. Exactly what that would be, I don't know without trying things out. My *guess* would be that adding JS_ENABLE_JIT to Makefile.in and using it only in the places you need here would be it. I'm not sure exactly what blocks you are talking about in comment 98, but it sounds like a good idea.
