commit 01cad84e1996a6f20bf19609d0554c73f2ee33d5

    Fix __printf_fp wmemset namespace (bug 17574).

    __printf_fp calls wmemset, but that is not an ISO C90 function.  This
    patch fixes it to call a new __wmemset name instead (with wmemset
    being a weak alias).

    Tested for x86_64 (testsuite, and that disassembly of installed shared
    libraries is unchanged by the patch).

        [BZ #17574]
        * wcsmbs/wmemset.c (wmemset): Rename to __wmemset and define as
        weak alias of __wmemset.  Use libc_hidden_weak.
        (__wmemset): Use libc_hidden_def.
        * include/wchar.h (__wmemset): Declare.  Use libc_hidden_proto.
        * stdio-common/printf_fp.c (___printf_fp): Call __wmemset instead
        of wmemset.
