* sysdeps/mach/hurd/bind.c: Translate EEXIST from dir_link into EADDRINUSE. If translated node doesn't grok ifsock protocol, return EADDRINUSE. * sysdeps/mach/hurd/connect.c: Make address arg `const struct sockaddr_un *'. The redecl is kosher and avoids another variable for AF_LOCAL case. * sysdeps/mach/hurd/sendto.c: Likewise. * sysdeps/mach/hurd/bind.c: Likewise. * socket/sys/socket.h (__SOCKADDR_ARG): Enable transparent_union code for GCC >= 2.7; use __transparent_union__ for name safety; add several sockaddr flavors. (__SOCKADDR_ALLTYPES, __SOCKADDR_ONETYPE): New macros used in constructing the transparent union declarations. (__CONST_SOCKADDR_ARG): New type (or macro if not GCC 2.7). (bind, connect, sendto): Make the sockaddr argument use that.
