It like to propose that for all those cases where we currently have USE_GCC, we try to make this USE_GCC=3.4+ because this will significantly reduce all the different scenarios our users may run into (and which we never tested) and GCC 3.4. is the system compiler for 5.x and 6.x. Also, it would be great could Kris do a pointyhat run where every USE_GCC=x.y+ (note the +) is translated to USE_GCC=4.1 or at least 4.0; this surely will help us shake out all sorts of bugs in ports.
