From my attempt at extending the __has_attribute check ;-) I discovered that there already is a test for __has_attribute, albeit in test/Lexer/has_attribute.cpp. Attached is a patch that merges both into the new test, as __has_attribute is handled in the preprocessor, not the lexer (I also took the liberty of adapting the test to clang's test framework).
