Some linknamespace test failures turned out to be because the variables in6addr_any and in6addr_loopback weren't listed in the lists of extra reserved symbols for the relevant standards (only functions are handled automatically through -aux-info, data symbols need listing manually in list-header-symbols.pl). This patch duly adds those symbols to those lists (there are still failures for older standards because of references to those symbols being brought in for standards that didn't reserve them: bug 18532, to be fixed separately). Tested for x86_64. * conform/list-header-symbols.pl (%extra_syms): Add in6addr_any and in6addr_loopback for XOPEN2K, XOPEN2K8 and POSIX2008. * conform/Makefile (test-xfail-XOPEN2K/netdb.h/linknamespace): Remove variable. (test-xfail-POSIX2008/netdb.h/linknamespace): Likewise. (test-xfail-XOPEN2K8/netdb.h/linknamespace): Likewise.
