>Description:
	A label in the generated grammer would never be used,
	removed.
	Extra set of parentesises around assignment in an if-
	statement to make lint happy
	Use prototype decl. of yyparse() if defined(__STDC__)
>How-To-Repeat:
	Run 'gcc -Wall' on yacc output
	Note that yyerrlab will be used if the YYERROR statement
	has been used in the grammar, and thus cannot be removed.
	It is also properly handled by lint
