Re: Interesting failures of 'cscope'

["Martin J. Bligh" <mbligh@aracnet.com>]

Various versions of cscope are buggy as hell, and I'm not at all sure the
recent ones are any better than older ones ... caveat user ;-)

Personally I use an old binary ripped off RH 6.2, which still seems to
work ... any current ones I've tried are broken.
