Yes, I also use -u as a matter of course.
It has saved me from many local/global variable conflicts.

I would be interested in trying your new parser generator,
if it's at that stage now.

I currently have 29 shift/reduce conflicts, which are
causing many false syntax errors.  I fixed some by using
yyerror to save (and later retrieve) the discarded tokens.
There must be better ways to do it, but it's been so many
years since I've used yacc that I've forgotten all the
techniques.

iyacc -i -d -v does not produce y.output.
I have to use iyacc -v (or bison -y -v) to get y.output.
 
I still don't know how to submit a bug report to Unicon's
bug tracker.  When I follow the links from Unicon.org,
all I can do is look at the bug reports.
