We used to warn about this before, but users contributed patches that got
merged that removed these warnings for qmake versions where this bug is
fixed (QTCREATORBUG-10024).

Oswald says this to the topic:
"it's possible that *some* related problems were fixed (i remember for a fact
that i tried), but the fundamental underlying reason is inherent in
fileFixify(). fixing it basically means rewriting half of qmake, which simply
isn't going to happen at this point."
