What do you mean by `stopped working'?  I changed them and all the tests
continued to pass.  Are these false results? Note that the changes in
calc.at depend on the changes in local.at.

I disagree.  There's no reason for parameters to yyerror() and to yylex()
to intrude on the parser's namespace.  I've noticed that the bison
documentation is careful about this.
