Changing ColLabel to ColId seems to have corrected the problem but now
I'm completely confused as to how it works. From the light reading I
did an hour ago off various websites about shift reduce conflicts
(where I found that %expect thing) was that the DEFAULT element would
be moved off the stack immediatly as it was a known element which
could not be reduced. Hence my thoughts it was the equal sign and
c_expr.
Seems Amazon will receive an order for a book on bison tomorrow.
