[boost] [system] - system_message and gai_strerror function

Hello, the system_message function is implemented with ::strerror. How to handle systems erros related like EAI_NONAME (host not found), EAI_MEMORY (allocation failure) etc.? This erros occure in the context of getaddrinfo (related to network address and service translation) and requier ::gai_strerror in system_message. regards, Oliver
