   I see nothing in the standard that prevents '_BitInt(64)' and 'long'   
   to be the same type.  And AFICS promotion rules are the only thing   
   which prevents 'uint8_t' and '_BitInt(8)' to be the same type.   
   Maybe I missed something, but I have read posts that appeared here   
   and I saw nothing indicating otherwise.
