Yacc %define parse.error verbose generates error - yacc

Question

When I try to get more out of my "syntax error", I seem to use the way described on so many websites, but all seem to create their own errors, for some reason.
I was getting standard "syntax error" on line 5 of the Input file... so I wanted to add better error handling so I can see what exactly is the issue. But
%define parse.error verbose
However, it gives me this;
error: %define variable 'parse.error' is not used
Below are my files, as long as you keep it constructive, feel free to comment on more then just the error parts, any help is welcome :)
(As long as the errors get fixed as well :P )
Thanks in advance!
