Yeah, I fed that output to g++, and then it compiles just fine. But when it's in the actual build with all the -MD -MT -MF flags, it doesn't. Those are, btw, in case it's of any help, -MD -MT qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o -MF qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o.d -o qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o
