Comment (by LenoreHorner):

 R @ 4.1.0 on Mojave with Xcode 11.3.1 still gives (on this OS with this
 Xcode):

 Warning: Configuration logfiles contain indications of -Wimplicit-
 function-declaration; check that features were not accidentally disabled:
   _NL_LOCALE_NAME: found in R-4.1.0/config.log
   objc_lookup_class: found in R-4.1.0/config.log
   objc_lookUpClass: found in R-4.1.0/config.log

 Because it built successfully, there's no log, but it seems like the
 implicit function declarations haven't been dealt with yet.
