HEAD broken

If anyone else has time these are highest priority.

I've run out of time myself to figure them out tonight:

(1)
buildtest_layer-00-default.log:configure: error: cfgaux/configure failed
for helpers/negotiate_auth/squid_kerb_auth

FWIW: It seems to be FreeBSD or auto-tools version related, the kerb
auth was tested and found without breakage on Linux /w autoconf 1.62
before commit.

(2)
This is way old and just uncovered. default handling of some option not
working or documented properly in ./configure

buildtest_layer-02-maximus.log:configure: error: Unsupported tag name: yes

(3)
a syntax error to do with "class std::exception" when past the configure
breakage.
