        <pre>struct Foo {
  void member() __restrict__ {
    Foo *__restrict__ This = this;
  }
};

Clang gives the diagnostic:

test.cpp:3:23: error: cannot initialize a variable of type 'Foo *restrict' with
      an rvalue of type 'restrict Foo *'
    Foo *__restrict__ This = this;
                      ^      ~~~~
1 error generated.

Clang seems to think that `this` has type `restrict Foo *` (restrict on Foo,
rather than the pointer)

The GCC extension says:

<<a href="http://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html#Restricted-Pointers">http://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html#Restricted-Pointers</a>>

"Within the body of T::fn, this has the effective definition T *__restrict__
const this."</pre>
