Well, I haven't thought that CC Mode supports yacc/bison well enough
to mention it as a supported language, even less add a major mode
called yacc-mode without tweaking the syntax recognition rules a bit
first.

Of course, I wouldn't mind taking patches that added a decent
yacc-mode. But until then, if anyone want to use C mode to edit yacc
files it's up to them to switch to it, knowing full and well that it's
intended for a different language. Perhaps it could mentioned
somewhere in the doc that C mode works fairly well to edit the C
blocks in yacc files, but otoh I think that's pretty obvious.

So the bottom line is that if there's a yacc-mode, or a default
binding for .y files to C mode, the expectations of the support for
that language will be higher than the code currently measures up to.
