this is note quite as easy to reproduce.  sorry.

the problem is that mkstemp() does not regard FIFOs (as created by
mkfifo() or mknod()) as existing files.

e.g.

  char s1[] = "/tmp/foo-XXXXXX";
  char s2[] = "/tmp/foo-XXXXXX";
  int fd = mkstemp(s1);
  close(fd); remove(s1);
  mkfifo(s1,0644);
  mkstemp(s2);
  strcmp(s1,s2) ===> 0

Do not worry about which side your bread is buttered on: you eat BOTH sides.
