You do get the above, provided the sources don't use some macro that changes 
on every build, like __RANDOM__ or __DATETIME__.

It's frowned upon to use __DATETIME__ because of that. I've removed __DATE__ 
from Qt 5.4:

rcc. The compiler produces bitwise identical builds for the same sources. The 
problem is that one source is changing.
