…aders Let's remove the `requires objc` from the module map file generated for the compatibility header. This condition triggered an error when importing the compatibility header from a C source file. This declaration is superfluous, the compatibility header is already printed in a way where the Objective-C code is protected behind a language check. C clients can safely import the current compatibility header even if they may not see any content. Let's lift this restriction. It isn't currently necessary and we're adding C content to the compatibility header with the official support for `@cdecl` that is independent of Objective-C.
