Ok, I'm not sure if this may cause any other issues, however I altered the
main.c code, line 858, from:
am_root = (getuid() == 0);
am_root = (geteuid() == 0);
It compiles without problem, and works perfectly under our conditions, and
also works without setuid root as a normal, non-root, user, and also returns
the correct uid for root when run without setuid root as root (if you see
what I mean). Basically it works with/without setuid root, inside or outside
a chroot jail with a root or non-root user as it should do.
