* 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@40053 138bc75d-0d04-0410-961f-82ee72b054a4
