* cppinit.c (builtin_array): Update.
(init_builtins): Flag builtins to warn if redefined or
undefined. Define __GXX_WEAK as a normal macro.
* cpplib.c (do_undef): Warn if flagged NODE_WARN.
* cpplib.h (NODE_WARN): New flag.
* cppmacro.c (builtin_macro): Remove handling of __GXX_WEAK__.
Handle __STDC__ as a builtin only on Solaris.
(warn_of_redefinition): Renamed from check_macro_definition.
Reverse sense of test. Always warn if NODE_WARN.
(_cpp_create_definition): Use warn_of_redefinition. Flag
any macro beginning with "__STDC_" to require a mandatory
warning if redefined or undefined.
