 > The root cause is that clang 12 enables `-Werror` by default. Not sure
 if Apple will roll back this feature.

 I don't think it's a blanket {{{-Werror}}}, but  they do generate an error
 on implicit function definitions, by default, as of Xcode12.

 Turning off the error can be done more specifically for that error as
 well, or you can build with a non-Apple clang compiler like macports-
 clang-10, however apparently if you fix the build that way, it remains
 broken on all the new Apple Silicon machines, that require a proper header
 and a proper function definition for every function.

 So MacPorts is not accepting the fix of turning off the error or building
 with a non-Apple clang compiler as a fix for this issue, as we'll all just
 have to come right back to this same issue again in a few months and fix
 it properly anyway.

 As a fix for your own personal system, no problem of course -- it's your
 system, you can do anything you want with it!
