Yup, that's in S5R3.1's <sys/errno.h> too, with the same comment; I'd
just done a quick "grep" and didn't see the "Convergent" stuff.

I would agree.  It's probably in AT&T's releases as a left-over from the
days of the 7300/3B1, which was a Convergent box.  I hope CTIX now uses
EDEADLK; I would suspect they do.
