* sunrpc/svc_authux.c (_svcauth_unix): Remove spurious printf (ugh!).
	* sysdeps/i386/bits/byteswap.h (__bswap_16, __bswap_32, __bswap_64):
	Evaluate argument exactly once.  Remove __volatile__ from asm's.

	* include/unistd.h: Use libc_hidden_proto for getdomainname
	and getlogin_r.
	* sysdeps/generic/getdomain.c: Add libc_hidden_def.
	* sysdeps/mach/hurd/getdomain.c: Likewise.
	* sysdeps/unix/getlogin_r.c: Likewise.
	* sysdeps/mach/hurd/getlogin_r.c: Likewise.
	* sysdeps/generic/getlogin_r.c: Likewise.

	* include/rpc/auth_des.h: Use libc_hidden_proto for rtime.
	* sunrpc/rtime.c: Add libc_hidden_def.

	* include/string.h: Use libc_hidden_proto for basename.
	* string/basename.c [_LIBC]: Add libc_hidden_def.

	* sysdeps/unix/sysv/linux/opensock.c (__opensock): socket -> __socket.

	* locale/loadarchive.c: munmap -> __munmap throughout.

	* include/netdb.h: Use libc_hidden_proto for gai_strerror.
	* sysdeps/posix/gai_strerror.c: Add libc_hidden_def.
	* sysdeps/generic/gai_strerror.c: Likewise.
