Hmm, yes...
But what I did:
I have a folder qt5 with the source tree. And one qt5-build.
In qt5-build I just did a ../qt5/configure. So I expected the
source tree to be untouched. But when I created this source tree,
I used this tree for the first time to try an out-of-source 
build with the qt sources. So I might have made a mistake earlier. 
Checking now.
