Zack Weinberg f2bea4da2e Installed-header hygiene (BZ#20366): conditionally defined structures. ... Several network-related structures are defined conditionally under __USE_MISC, but unconditionally used by other headers. The path of least resistance is usually to condition the uses on __USE_MISC as well. * 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. sys/socket.h defines struct osockaddr only under __USE_MISC, whereas protocols/talkd.h requires it unconditionally. Here it doesn't make sense to condition the entire body of protocols/talkd.h on __USE_MISC. Rather than complicate sys/socket.h with a __need macro or duplicate the definition, I am introducing a new concept: tiny headers named bits/types/TYPE.h that define TYPE and nothing else. This can, I hope, ultimately replace *all* the __need macros. The guard macro for such headers will be __TYPE_defined, just in case application or third-party library code is looking at them. * 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.		2016-09-23 08:43:56 -04:00
