Sounds good. A simple text replace of s/auto_ptr/unique_ptr/ works
perfectly for me, can someone with gcc 4.4 test this? If no volunteers,
I can use a VM to test.

NB: We currently work with gcc ~>= 4.1, this will effectively bump the
minimum version to 4.4. Not a bad thing, just noting. As you said,
released in 2009, available since Debian 6 (2011), RHEL/CentOS 6 (2011),
and any current Ubuntu (2012 or newer).

That was the only new warning I've seen, and make check passes for me.
I'm using gcc 5.3.1 with -std=gnu++11.
