`__cpp_deleted_function` should be set only for C++26 and higher. It is set even for C++20 now (https://godbolt.org/z/T7Ph3E4fz), which makes the following code:
```cpp
[[nodiscard]] friend consteval Unit auto operator*(Unit auto, Magnitude auto)
#if __cpp_deleted_function
= delete("To scale a unit use `mag * unit` syntax");
#else
= delete;
#endif
```
result in the following error on C++20 build:
```text
unit.h:154:14: error: '= delete' with a message is a C++2c extension [-Werror,-Wc++26-extensions]
154 | = delete("To scale a unit use `mag * unit` syntax");
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
