The problem the user is experiencing is not the result of any "-Werror" in any Makefile; rather, it is the result of the fact that Apple changed implicit declaration of functions from a warning to an error in Xcode 12. The fix is not to attempt to turn the error back into a warning again. The fix is to define functions before you use them.

The user does not care what the developer's fix is. He just wants the
DoS gone so he can use his software.
