Well, Xcode 5.0 will be dropping support for GCC, so the only way to target
10.6 or below will be with clang + libstc++.
Supporting 10.6 is a huge priority given that version has the largest market
share of all OS X versions (about 35%). Do we really want to wipe out over a
third of potential end-users of Qt-based products? Dropping support for it at
this point is an absolutely terrible idea, and 10.9 is not even revealed yet.
Secondly, it appears that the patch in question does not force use of libc++
("Users who wish to deploy to 10.6 need to build their own Qt, passing
-no-c++11 to configure.") unless I am missing something.
It would be irrelevant if Snow Leopard were 10 years old; what really matters
is the fact it maintains a massive 35% market share of OS X versions and
therefore is critical to provide support for. Most popular software packages
seem to have recently switched to 10.6 as a minimum (Firefox, Chrome, Skype, to
name a few).
10.5 came out in 2007 and was dropped by Qt in 2012. 10.6 came out in 2009 so
let's drop 10.6 somewhere around 2015 or even 2016 (I add a year because of its
higher market share). We should have 10.11 by then.
