swscanf (added in C90 Amendment 1, present in UNIX98) calls vswscanf (added in C99, not in C90 Amendment 1 or UNIX98). This patch fixes this by using __vswscanf instead and making vswscanf into a weak alias. (I intend to add conform/ test support for C90 Amendment 1 - and various other standard versions supported by glibc but not yet by conform/ tests - at some point, once the results for currently tested standards are cleaner.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18542] * libio/iovswscanf.c (__vswscanf): Use libc_hidden_def. (vswscanf): Use ldbl_weak_alias instead of ldbl_strong_alias * include/wchar.h (__vswscanf): Declare. Use libc_hidden_proto. * libio/swscanf.c (__swscanf): Call __vswscanf instead of vswscanf. * conform/Makefile (test-xfail-UNIX98/wchar.h/linknamespace): Remove variable.
