This patch is still distributed with procmail-3.13.1-2.
Thankfully, it is not actually used any more -- the patch
line in the spec file is commented out, though unfortunately
with no comment.
I suggest a comment at least, pointing out just how bad it
would be to disable fcntl() locking now that kernel 2.2 uses
that for NFS. (It's used for cache coherency as well as
locking with the 2.2 NFS client).
I suggest the patch be removed, or even replaced with one
that explicitly uses "100" instead of "000".
The patch is supplied as a reference to people who might be
trying to use later versions of a package on earlier versions
of an operating system.
As for locking, Red Hat since 5.2 uses *only* fcntl locking for
