notice that before bison 2.0 you did not had neither this messages :)

I reported the strange messages around ruby-talk:179793 and matz said he 
did not know of a way to get better error messages.

In ruby-talk:182173 I reported that there is a siple solution, at least 
for some things, but I don't know if someone in ruby-core/dev ever read 
or considered that, I guess providing a patch to parse.y would be 
helpful :)
