I think it is a bug that --disable-error-checking disables warnings, but
with a name like that, it is really hard to say what the option ought to
do. I suggest filing a bug report and try to convince others that the
./configure option should not disable warnings (and should probably be
renamed to match what it does).

Meanwhile, you can

* use CXXFLAGS (and possibly other ./configure variables) to manually
disable -Werror (see ./configure --help) or

* edit acinclude/compiler-flags.m4 (and possibly other files) to remove
-Werror added by Squid (you will need to bootstrap and configure after
that).

Cheers,

Alex.
