Is this check still needed? Since @BumblingCoder switched the loader to QLibrary, it can be removed safely. If there are some reason to keep this, however, leaving is okay, too.

It should be safe to run the code on all platforms. Pointless on the ones it is disabled on, but safe.

It saves a few cpu cycles to preprocess it out. I agree with the logic, especially when loading libraries. Why add an unnecessary step to MainWindow for systems which can't experience the bug?

Okay then. Keep it if leaving makes sense.

Should line 1500 have this change as well?
