my bad; is_root is a helper function i provided as part of this file;
the latest version which should work in your posix system AND was
specifically written to hopefully not break with NON-STOP based on
what you told us about it looks like (hand edited and not tested) :

is_root() {
  id -u >u
  id -u root >r
  cmp u r
}
