This isn't exactly the question that is being asked, but why GCC
4.7? Is it a particular feature that it provides, or is it
important for other reasons?<br>
<br>
When talking about GCC versions, I like to look at the version
bundled with various Linux distributions.<br>
Ubuntu 12.04 LTS (precise), released Apr-26-2012: GCC 4.6.3<br>
Ubuntu 14.04 LTS (trusty), released Apr-17-2014: GCC 4.8.2<br>
RHEL 6, released Nov-10-2010: GCC 4.4.7<br>
RHEL 7, released Jun-10-2014: GCC 4.8.3<br>

<div>We're having more and more trouble supporting pre-4.7
versions of gcc, especially in C++03 mode.</div>
<div><br>
</div>
<div>
<div>Much of the early gcc support was driven by the fact that
Apple was never going to move past gcc 4.2.1, and the
necessity of supporting that compiler - but that ship has
sailed.</div>
</div>
<div><br>
</div>
<div>I'd like to officially drop support for those compilers.</div>
