Comment (by chrstphrchvz):

 PR opened: https://github.com/macports/macports-ports/pull/9399

 No update on whether upstream plans to change anything, but one maintainer
 remarks:
 >Implicit function declarations are legal in C89 but not in C99 or C++.
 Apparently Apple decided not to care about C89 in their new ARM64 ABI.
 This means that disabling this error probably causes either vararg or non-
 vararg implicitly defined function calls to be broken, but it doesn't give
 much of a hint which one of the two.
