The change in behaviour is from newer autoconf being used to generate
the code tarballs. One of the reasons for that was to get better/easier
cross-compiling support.

You should only** have to specify the ./configure options to tell it
which OS the compile is happening on (--build=X) and which OS type will
run the binary (--host=Y).

What exactly is the failure you are encountering?

** besides having the appropriate *-dev library versions installed for
cross-compiling against and tools that can cross-compile.

Not required. "Preferred" is the word for it. We have code to make use
of some C++11 only when available. Mostly we are taking advantage of the
increased compiler code checking in our build farm to remove bugs before
anyone notices them :-)

The switch to mandatory C++11 support for general builds is still being
discussed on squid-dev and IRC as to when the timing would offer least
pain for everyonea and how long we can procrastinate on it. It might
happen around Squid-3.6.

Any GCC 4.0+ (excluding 4.5 with broken stdlib definitions of
auto_ptr/unique_ptr) should work fine for Squid-3.2 and later. The later
versions are better though with more general C++11 support benfits than
the older ones.
