[Bug c++/41815] New: GCC wrongly treats rvalues of non-class type cv-qualified

[schaub-johannes at web dot de]

The issue rises up with C++0x's decltype and rvalue references:

int const f() { return 0; }

int &&r = f(); // binding "int&&" to "int" should succeed
decltype(0, f()) i; // "i" should get type "int", not "int const". 

In C++, non-class type are not cv-qualified.
