A possible solution to this conundrum is to allow two C overloads of the same
function name if they are defined in the same scope. They'd be disallowed if
they were in different scopes. The latter would most likely be accidental. A
possibility would be to disallow it unless the declarations are both @system.

I still don't understand why this is not treated as an error. It's obviously
generating incorrect C ABI's in this case. If it's used to support a specific
(or deprecated) path it needs to be deprecated or warning (ugh) so that we can
remove the parts that rely on it and get to a conforming state.

This was invented as a tool to deprecate callbacks missing those attributes.
There is unfortunately no wildcard to infer function attributes from parameter
(callback) attributes, though this use-case comes up frequently (e.g. in
interface and class methods besides extern(C) methods).

"GetMonitorInfoA" is also overloaded in this way in druntime,
