From 475cef58f96d1d274e5c7b448df7231415783af0 Mon Sep 17 00:00:00 2001 From: "Bradley T. Hughes" Date: Sat, 4 Feb 2012 14:20:32 +0100 Subject: Move compiler detection from qglobal.h to a separate header qcompilerdetection.h is included from qglobal.h, and does all Q_CC_* and compiler feature detection.
