The data has to be passed, within one architecture, from Ada to C and vice versa, through files, tcp/ip "messages", calls to libraries. The code (Ada and C) has to run on several architectures, it provides, by instance, interface to UNIX calls. As an example, just consider that a file size, of type "long" in C, can be implemented on 32 or 64 bits, depending on the operating system.
