[yschimke]

enum ImageState {
    IMAGE_STATE_UNSPECIFIED = 0;
    IMAGE_STATE_READONLY = 1;     /* unlocked */
    IMAGE_STATE_MUSTLOCK = 2;     /* must be locked */
    IMAGE_STATE_LOCKED = 3;       /* locked */
    IMAGE_STATE_LOCKED_EMPTY = 4; /* locked and empty */
    IMAGE_STATE_TEMPORARY = 5;    /* copied to temp file (no lock needed) */
}

fails with

Check seems harsh

        // Ensure nothing follows a trailing star comment.
        while (pos < data.size) {
          val c = data[pos++]
          if (c == '\n') {
            newline()
            break
          }
          expect(c == ' ' || c == '\t') { "no syntax may follow trailing comment" }
        }
