Wow that title is a mouthful. Here's a concrete example:
```c++
extern const __declspec(selectany) struct { int x; } foo = { 42 };
```
clang-cl gives the error:
```
> clang-cl main.cpp
main.cpp(2,25): error: 'selectany' can only be applied to data items with external linkage
2 | extern const __declspec(selectany) struct { int x; } foo = { 42 };
| ^
1 error generated.
```
Of course, if you give the struct its own definition, the code compiles fine:
```c++
struct bar { int x; };
extern const __declspec(selectany) bar foo = { 42 };
```
MSVC compiles both without issue.
