commit be7dc2b77e368daad6f81e272fc41f1b86166240
Author: Joseph Myers <joseph@codesourcery.com>

    Fix syslog dprintf namespace (bug 18534).
    
    syslog functions bring in references to dprintf, which wasn't added to
    POSIX until the 2008 edition and so isn't in various standards
    containing the syslog functions.  This patch fixes this by making
    dprintf into a weak alias of __dprintf and using __dprintf as
    appropriate.
    
    Tested for x86_64 and x86 (testsuite, and that installed stripped
    shared libraries are unchanged by the patch).
    
    	[BZ #18534]
    	* stdio-common/dprintf.c (__dprintf): Use libc_hidden_def.
    	(dprintf): Define as a weak alias of __dprintf, not a strong
    	alias.
    	* include/stdio.h (__dprintf): Declare.  Use libc_hidden_proto.
    	* misc/syslog.c (__vsyslog_chk): Call __dprintf instead of
    	dprintf.
    	* conform/Makefile (test-xfail-XPG4/syslog.h/linknamespace):
    	Remove variable.
    	(test-xfail-UNIX98/syslog.h/linknamespace): Likewise.
    	(test-xfail-XOPEN2K/syslog.h/linknamespace): Likewise.
