Bug#876901: QFINDTESTDATA uses __FILE__

It's not, Microsoft doesn't do it. Last time I checked, QT is supposed to work on Windows.

That's false, you're misleading casual readers when you say this. *None* of them define it using the word "path", they all use the word "name" - except the GCC docs which say:

"path by which the preprocessor opened the file, not the short name specified in ‘#include’ or as the input file name argument."

Let me highlight that for you: "not [..] the input file name argument".
