c-common.c (c_common_init): -Wtraditional also implies -Wlong-long.
* c-common.c (c_common_init): -Wtraditional also implies -Wlong-long.
* cppinit.c (cpp_post_options): Likewise.
* cppexp.c (cpp_classify_number): Suppress -Wtraditional
warning about 'LL' suffix (but not 'ULL' etc) when
-Wno-long-long is in effect.
* cppmacro.c (_cpp_builtin_macro_text) [BT_TIME, BT_DATE]:
Check for failing time()/localtime(), issue a warning, and
make __TIME__ and __DATE__ expand to fallback strings.
* doc/cpp.texi, doc/extend.texi: Document behavior of __DATE__
and __TIME__ when the date and time cannot be determined.
