Quoting from the compiler manual, there's an option to suppress this
warning for individual functions:

   {nowarn_unused_function, FAs}

   Turns off warnings for unused local functions as
nowarn_unused_function but only for the mentioned local functions.
   FAs is a tuple {Name,Arity} or a list of such tuples.

So you can just put lines like this in your included header:

   -compile({nowarn_unused_function, data_conn_make_inet_link/4}).
