The kernel was compiled on Dec 19th (sorry, should have had that info
in the origional mail), and I was just looking at the program which
was running at the time, and it does nothing more complicated than
basic I/O. It's called from some shell script tho. Could csh do this
setgroups() call? I'll do an update of the source tree to make sure
that the sources are reasonably up-to-date, but I'm fairly sure I did
update just before I compiled the kernel.
