    Description

      https://codereview.qt-project.org/c/qt/qtbase/+/511801 broke -unity-build's in which qfilesystemengine_unix.cpp ends up in the same unity_cxx_nn.cpp as qstorageinfo_linux.cpp.

      While this affects only certain glibc's, Unbuntu 20.04 is affected. The internet suggests to not mix the two APIs in one executable, due to ODR violations (MS_ flags are #define'd in one and an enum in the other).
