The proper fix would be fix gnat-4.4 and binNMU/requeue affected packages.

There is a big difference between (kernels of) Linux and FreeBSD in this:

Linux:
       struct sockaddr {
               short       sa_family;
               char        sa_data[14];
           }


FreeBSD:
       struct sockaddr {
               unsigned char sa_len;
	       unsigned char sa_family;
               char          sa_data[14];
           }

Ada bindings have to closely follow definition of this struct.
