The compiler error does not give the cause of the error.
The code is trying to use the __weak_reference built-in or macro or
whatever it is to create weak references for these functions, however
the macro isnt defined so clang treats those lines as function
declarations.
They are not function declarations and your patches solution for them
is not correct, but I cant see how gcc is meant to deal with these
though.
