<pre>
    The following C++ code is not compiled with clang x86-64 v13.0.0 with MS extensions enabled, while it compiles successfully with X86 msvc v19.
Steps to reproduce:
1. cat test.cpp
```
#include <type_traits>

int * __ptr32 f() { return 0; }

int main()
{
  std::remove_reference<decltype(*f())>::type a = 1;
  return 0;
}
```
2. clang test.cpp -S  -fms-extensions

```
test.cpp:20:47: error: automatic variable qualified with an address space
  std::remove_reference<decltype(*f())>::type a = 1;
                                              ^
1 error generated.
```

Seems like std::remove_reference does not provide a correct type:
clang -  __sptr __ptr32 int // attributes need to be removed as well
msvc -  int
