Should this warn about `wchar_t` in C?
```c
#include <wchar.h>
int main (void)
{
wchar_t foo;
(void)foo;
return 0;
}
```
```
% xcrun /Users/builder/llvm/llvm-install/bin/clang -fsyntax-only -Weverything
~/Desktop/test.c
/Users/builder/Desktop/test.c:5:3: warning: identifier 'wchar_t' conflicts with
a C++ keyword [-Wc++-keyword]
5 | wchar_t foo;
