freebsd/usr.bin/xlint/lint1/op.h
Joerg Wunsch 96a322df43 Jochen Pohl's lint(1) from NetBSD. Yet another import.
This is just a vendor import by now.  I'll wait until i'll get the
imported files back via CTM before applying the FreeBSD patches.
Don't use it yet.

Submitted by:	Jochen Pohl <jpo.drs@sni.de>
Obtained from:	(NetBSD -- this version is directly from Jochen)
