Hi,

Here are some directives which we should be including in the squid.spec file. 
These simply add support for more helpers (digest), they do not directly affect
the squid binary itself.

--enable-auth="basic,digest,ntlm"           (digest is new)
--enable-digest-auth-helpers="password"      (digest auth helper)
--enable-ntlm-auth-helpers="fakeauth,no_check,winbind"   (including fakeauth -
handy for testing)

Also, is there a reason why we are using  --enable-truncate  ?  I would tend to
suggest eliminating this option, -unlinkd is arguably slightly slower, but means
we are less likely to run out of inodes.
Anyone who is running a high performance or very busy proxy with squid should
know how to tune their system and make this change themselves, if they feel it
is important.  But for smaller installations where minimal configuration is
required, I would think that elimination of this configure option is actually an
overall gain.
