[gdal-dev] C++11 timeline

Currently, at least:
GCC >= 4.4 (actually must be 4.1 since this is what ancient mingw uses)
clang >= 3.something (3.0 probably)
VS >= 2008
ICC 15 probably

One aspect is to also consider the various analyzers used. I think cppcheck has only partial C+
+11 support. I'd guess Coverity Scan should have decent C++11 support but this is just a 
guess. CLang Static Analyzer should likely work just fine with the C++11 supported by the 
underlying clang compiler

GCC 4.8 is needed for C++11 I think. There are folks using recent GDAL on older distros like 
Ubuntu 12.04 (which ships with gcc 4.6). I guess they could switch to adding a PPA with a 
more recent toolchain.
For Visual Studio depends on the features we use. Would be good to have VS2013 or even 
2012. I'm CC'ing Jürgen Fischer to know if he has plans regarding of the compiler version that 
will be used for OSGeo4W / QGIS 3.0
