See https://github.com/cplusplus/CWG/issues/422.
In short, it is currently unclear what constitutes "use" of the `main` function and Clang implements this very aggressively. It is the only compiler which flags `decltype(main)`.
My suggested solution for the issue in [[basic.start.main] p3](https://eel.is/c++draft/basic.start.main#3) is
```diff
The function main shall not be
-used
+odr-used
within the program.
```
This would invalidate the current behavior because `decltype(main)` is not odr-use.
Is there a strong reason for LLVM to flag `decltype(main)` or is the suggested solution acceptable?
