__linktime_error() does the same thing as __compiletime_error() and is
only used in bug.h. Since the macro defines a function attribute that
will cause a failure at compile-time (not link-time), it makes more
sense to keep __compiletime_error(), which is also neatly mated with
__compiletime_warning().
