Yeah. The warnings stem from the fact that QT_LARGE_FILE_SUPPORT is both defined in qconfig.h (written by configure) and the compiler call in the makefile (generated by qmake).

That'll work, but I also understood that you only get them if passing '-largefile' to configure. If you skip that, you don't get warnings either, right?
