	I thought 3.2.0.9 was latest stable in that series...my bad.

	That's actually the server name.   This one is still a bit
perplexing, but not going to worry about it.

	Well, they gave me things to look for as to why things weren't
working... ;-)....

	Oddly enough I was getting MANY sig6's in suse's build and their's
is 3.1 based.  But it might be related to the directory they have 
configured for *squid*'s  'system shared state dir' (/comm in configure), 
is /var/squid, which I found missing, so maybe that was causing problems
with the stock suse rpm, though it wasn't working as well as the version
I'd build from 3.0-HEAD....

	It doesn't use what's from 'configure'?
	Suse's config process uses a val of prefix=/usr, so
it would have been trying to use '/usr/var/run', which would
be a problem... ;-)

	I would, and will probably try 3.2 again, as I a multicore
machine that I run squid on.  But to solve my problem, I gave up
on 3.2 for the nonce, and did a make from 3.HEAD (which a cron
job keeps updated daily).   I was surprised/'didn't get' that 3.HEAD
was only a devel-branch for 3.1 -- as the 3.2 incompat's/probs I had
in converting, on top of using the wrong (too 'new') version, all went
away when I went back to a build from 3.HEAD.
	I could have resorted to backups, but wanted to work forward.
	Am working through several follow probs from my server distro
upgrade (lots of consequential problems in refixing config stuff...)..
So when I get back to a stable 'network', Maybe I'll try finding the
3.2.HEAD (am presuming that's what it would be called...)....
	Glad to hear I wasn't just running into not knowing how
to configure something and that you've already fixed real probs.
	All an interesting diversion ...
	Thanks for the explanations...now that I know about 3.2 and its
features, I'm wanting to get it working...
