Oracle C++ fails two preprocessor tests. I boiled it down to:

#define SOME_MACRO(x,y) some_result
int main() { SOME_MACRO();  return 0; }

Of course calling SOME_MACRO without two arguments is a preprocessor 
error. Oracle C++ gives only a warning.

My point is not about an actual bug but that a compiler decides a bug is 
not a bug because it gives a warning rather than an error. I find this 
ludicrous. I know that the VC++ preprocessor is much worse and is not 
even remotely C or C++ standard conformant. But no one from Microsoft 
would seriously argue that their preprocessor conformed to the C++ 
standard. The fact that the Oracle developer actual argues this case is 
what bothered me and caused my to give up trying to test that compiler 
or report anything to them.
