If I understood correctly, his idea is that from the point of view of Qt, 
the flag would be a RUNTIME flag. It would be passed by some inline code in 
the application that depends only on the compile-time flags for the 
APPLICATION, not for the Qt library. So different applications can use 
different settings with the SAME Qt binaries.
