I find these reports interesting, considering the fact that an
examination of ckutio.c shows that -DSAVEDUID does nothing unless
-DSETREUID is also used.  If you use both of them, then you get that
irritating warning from setreuid().  Are you running it setuid root?

I've had to use the patch below ever since the setreuid() warning was
put in.  I'll have to try submitting my prettied-up version of it to
C-Kermit's author again.  My kermit binary is setuid to uucp, and my
/etc/ttys sets the clocal flag on /dev/tty00 (my modem's com port).
