Can't sensibly test unless the compiler does support raw strings, since any test that would catch qmake's (prior) inability to parse raw strings would necessarily confuse the C++ compiler in the same way. This even applies (in test app code) to any #if-ery around the raw string, since tokenization happens before preprocessor directives are resolved. So the #if-ery on Q_COMPILER_RAW_STRINGS has to be in tst_qmake.cpp, not the test app it builds.
