This reverts commit f2583f3acf596cc545c8c0e3cb28e712f4ebf21b.
There is a large body of non-conforming C-like code using format strings
like this:
#define PRIuS "zu"
void h(size_t foo, size_t bar) {
printf("foo is %"PRIuS", bar is %"PRIuS, foo, bar);
}
Rejecting this code would be very disruptive. We could decide to do
that, but it's sufficiently disruptive that I think it requires
gathering more community consensus with an RFC, and Aaron indicated [1]
it's OK to revert for now so continuous testing systems can see past
this issue while we decide what to do.
