        (start_function): Make warning about implict int return type be a
        pedwarn in C99.
        * c-lex.c (yylex): Don't warn about `long long' in C99.
        * c-typeck.c (c_expand_return): In C99, always pedwarn about
        `return' with no value in function returning non-void.

        * c-typeck.c (pedwarn_c99): New.
