The Qt BC guarantee should only cover Qt. It should explicitly exclude 
compiler switches, libc, stdlib, boost, libclang, ... libraries.

IOW: Qt guarantees that:

1. two different patch releases of the same Qt minor release are binary
   compatible with each other, and
2. that a younger minor release is binary compatible with any older minor
   release of the same major Qt release,

provided the same external libraries, and the same toolchain are used to build 
the two Qt releases.

Thanks,
Marc
