Got the message after I sent mine. Since I'm not even a beginner on 
yacc/bison, I'll leave this to experts.

You're right of course, it shouldn't just look in the current 
directory. On Windows, the most common method is to search the 
current directory first, then the PATH. Would that be too uncommon on 
Unices?

I would prefer not having to set an additional environment variable, 
but it can be done if necessary. And same with a Windows registry 
entry; prefer not to, but it can be done.
