This should correspond to the definition of memcmp in usr/include/string.h and keep it from being a source of confusion for the compiler.

On Linux we're getting the opposite error now:

Cross-reference to 'memcmp.with type (Optional<UnsafeRawPointer>, Optional<UnsafeRawPointer>, Int) -> Int32' in module 'CDispatch'

instead of the previous error on macOS: (The error format changed since then and I'm there's a problem in it.)

*** DESERIALIZATION FAILURE (please include this section in any bug report) ***
top-level value not found
Cross-reference to module 'Darwin'
... memcmp
... with type (UnsafeRawPointer, UnsafeRawPointer, Int) -> Int32
