+	* sysdeps/mach/hurd/net/if_ppp.h
+	* sysdeps/unix/sysv/linux/net/if_ppp.h:
+	Only define struct ifpppstatsreq and struct ifpppcstatsreq
+	if __USE_MISC is defined, to ensure struct ifreq is declared.
+
+	* inet/netinet/ether.h: Condition all function prototypes
+	on __USE_MISC, to ensure struct ether_addr is declared.
+
+	* socket/bits/types/struct_osockaddr.h: New header.
+	* include/bits/types/struct_osockaddr.h: New wrapper.
+	* socket/Makefile: Install the new header.
+	* socket/sys/socket.h, inet/protocols/talkd.h:
+	Refer to bits/types/struct_osockaddr.h for the definition of
+	struct osockaddr.
