It doesn't seem to compile with clang either, at least not as of r235777:=


/usr/src/bin/expr/expr.y:291:2: error: implicit declaration of function '=
yyparse' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
        yyparse();
        ^

Note that it looks like the expr.c file is still generated with the
system yacc, so I'm not entirely sure what's going on here...
