Error Handling Bison
--------------------

int yyerror(s)
	char *s;
{
	printf("%s\n", s);
	return(-1);
}

flex generates the c-based scanner in lex.yy.c
bison generates the parser in minicex1.tab.c
yyerror()

#include "minicex1.tab.c"
#include "lex.yy.c"
#include "yyerror.c"
#define YYERROR_VERBOSE

int main()
{
	yyparse();
	return(1);
}
