Joseph Myers 12404bb04e Fix stdio.h cuserid namespace (bug 19989).
stdio.h declares cuserid if __USE_XOPEN.  But this was removed in the
2001 edition of POSIX.

The #endif comment "Use X/Open, but not issue 6." reflects the correct
logic, but does not correspond to the #ifdef.  The use of a correct
libc-hacker.  The online archives for libc-hacker in August 2000 are
broken, but the messages can be found in the qmail archives in
/sourceware1/qmail/lists-sourceware/libc-hacker/archive/26 if you have
shell access to sourceware.

The issue showed up in August 2000 because of a warning about a
non-prototype definition in sysdeps/posix/cuserid.c when there was no
previous prototype declaration.  Since we've now eliminated
non-prototype function definitions, that issue does not apply.  The
other points from that discussion were about whether it should be
included in _GNU_SOURCE; whether _GNU_SOURCE should include
"everything"; whether deprecated interfaces such as this should be
excluded from it; and whether, even given exclusion of deprecated
interfaces, it should apply for deprecations in a version of POSIX
that at that time had not been released.

This patch follows the more conservative approach to a fix of keeping
the interface in _GNU_SOURCE.  That matches how L_cuserid is handled.
I think there is a strong case for eliminating this interface from
_GNU_SOURCE (but this may not automatically be the case for every
interface removed in newer POSIX versions), but then L_cuserid should
also be removed from _GNU_SOURCE (in stdio-common/stdio_lim.h.in) at
the same time.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	[BZ #19989]
	* libio/stdio.h (cuserid): Do not declare if
	[__USE_XOPEN2K && !__USE_GNU].
	* conform/Makefile (test-xfail-XOPEN2K8/stdio.h/conform): Remove
	variable.

This directory contains the sources of the GNU C Library.
See the file "version.h" for what release version you have.

The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system.  It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.

The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[4567]86-*-gnu.  The current
GNU/Hurd support requires out-of-tree patches that will eventually be
incorporated into an official GNU C Library release.

When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 3.2 or later on all architectures except
i[4567]86 and x86_64, where Linux kernel version 2.6.32 or later
suffices.

Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.

The GNU C Library supports these configurations for using Linux kernels:

	aarch64*-*-linux-gnu
	alpha*-*-linux-gnu
	arm-*-linux-gnueabi
	hppa-*-linux-gnu	Not currently functional without patches.
	i[4567]86-*-linux-gnu
	x86_64-*-linux-gnu	Can build either x86_64 or x32
	ia64-*-linux-gnu
	m68k-*-linux-gnu
	microblaze*-*-linux-gnu
	mips-*-linux-gnu
	mips64-*-linux-gnu
	powerpc-*-linux-gnu	Hardware or software floating point, BE only.
	powerpc64*-*-linux-gnu	Big-endian and little-endian.
	s390-*-linux-gnu
	s390x-*-linux-gnu
	sh[34]-*-linux-gnu
	sparc*-*-linux-gnu
	sparc64*-*-linux-gnu
	tilegx-*-linux-gnu
	tilepro-*-linux-gnu

If you are interested in doing a port, please contact the glibc
maintainers; see http://www.gnu.org/software/libc/ for more
information.

See the file INSTALL to find out how to configure, build, and install
the GNU C Library.  You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.

The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory.  The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.  For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below.  Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.

Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information.  We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software.  See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.  License copyright years may be
listed using range notation, e.g., 1996-2015, indicating that every year in
