This was first reported in clangd/clangd#1543 and I was told that it should be reported here.
Clang incorrectly warns definition in unnamed namespace in header file.
```c++
// test.hpp
namespace a {
namespace /*b*/ {
static int c[[maybe_unused]] = 42; // even static doesn't help
}
}
```
```c++
test.hpp|3 col 16 warning| Variable 'c' defined in a header file; variable definitions in header files can lead to ODR violations [misc-definitions-in-headers]
```
However, this only happens in unnamed namespace. If I uncomment `b`, the warning is gone.
