$ pwd
/opt/build/libunistring-0.9.3/tests
$ cat ,t.c
#include <stdint.h>
#include "intprops.h"
int main (int argc, char **argv) {
  printf("%lx\n", (unsigned long) TYPE_MAXIMUM (uint_fast8_t));
  printf("%lx\n", (unsigned long) UINT_FAST8_MAX);
  return 0;
}
$ cc -I. -I../lib -o ,t ,t.c || echo fail
$ ./,t
ffffffff
ffffffff
$ cc -I. -I../lib +DD64 -o ,t ,t.c || echo fail
$ ./,t
ffffffff
ffffffffffffffff

% grep uint_fast8_t ./lib/stdint.h
lib/stdint.h:#undef uint_fast8_t
lib/stdint.h:typedef unsigned long int gl_uint_fast8_t;
lib/stdint.h:#define uint_fast8_t gl_uint_fast8_t
