If you're using genuine yacc then look for a file
called yaccpar that probably lives in /usr/lib.
If you're using bison the analogous files are
bison.hairy and bison.simple and they often live
in /usr/share
The files in question are basically include files by
another name and are simply copied into the generated
parser sourcecode.
