... and so it should be.  This is one of the famous system bugs of
the MINIX operating system, for which at least three people announ-
ced decent fixes.  The accompanying bug is, that group execute
permission does not work.  So, if you have:

-rwsr-s--- uucp   uucp   /usr/lib/uucp/uucico

and if your ID is "some_uucp.uucp", then you cannot execute the
program either.... Hurray!

I fixed both of these; it required three lines of code in MM and five
lines in FS.  That's all..

If people want to, I can post it, although other fixes were also
posted.

Fred.
