 CPPFLAGS are used for both C and C++ code but implicit function
 declarations are a C compiler warning. That flag should not be used for
 C++ code. (clang++ does not warn but g++ does: `cc1plus: warning: command-
 line option '-Wno-implicit-function-declaration' is valid for C/ObjC but
 not for C++`)

 Instead of turning off the warning entirely, it's better to turn the error
 back into a warning with `-Wno-error=implicit-function-declaration`. If we
 disable the error, we should also mark the port as incompatible with
 arm64.

 If you have a patch for your work in progress on quashing these issues,
 please attach it!
