toplev.c (lang_options): Add -Wlong-long, -Wno-long-long options.
* toplev.c (lang_options): Add -Wlong-long, -Wno-long-long
options.
* c-decl.c (warn_long_long): Define.
(c_decode_option): Parse -Wlong-long, -Wno-long-long options.
(grokdeclarator): Add flag `warn_long_long' as guard for

-Wno-long-long.
* gcc.1: The same as above.
* cp-tree.h (warn_long_long): Define.
