Subject: [PATCH] [HACK] Disable __has_builtin for now
This is only used for detecting __builtin_add_overflow, but since
we use gcc as a preprocessor for cproc, we have no way to tell it
we don't support that feature. Since the built-in is used regardless
of __has_builtin on gcc 5.1 or newer, just disable it for now until
the cproc preprocessor is complete.
