The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and
-D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4".
That naming is misleading. _XOPEN_SOURCE_EXTENDED actually means
XPG4.2, including UX-shaded interfaces. _XOPEN_SOURCE actually means
XPG4, or XPG4.2 without UX-shaded interfaces. (Prior XPG versions
also used _XOPEN_SOURCE, but without any versioning of the values of
the macro, so XPG4.2 without UX-shaded interfaces is the only sensible
set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without
_XOPEN_SOURCE_EXTENDED defined.)
This patch fixes the naming in the conform/ tests, so that what is now
called XPG4 is changed to XPG42, and what is now called XPG3 is
changed to XPG4.
Tested for x86_64 (and verified the complete set of expectations is
unchanged by the patch beyond the intended renaming).

MIPS o32 struct stat has the wrong type of st_rdev. This patch XFAILs
that test in the conformtest expectations for this case (the bug
should not be closed without an actual fix, however).
Tested with build-many-glibcs.py.
[BZ #21278]
* sysdeps/unix/sysv/linux/mips/mips32/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): Update comment.
* conform/data/sys/stat.h-data (stat.st_rdev): XFAIL for
mips-o32-linux.
This patch XFAILs the conformtest tv_nsec tests for x32 so that the
incorrect type does not potentially hide other failures. As this is
not a fix for the bug, it should remain open in Bugzilla.
Tested (compilation only) with build-many-glibcs.py.
[BZ #16437]
* sysdeps/unix/sysv/linux/x86_64/x32/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): New variable.
* conform/data/signal.h-data (timespec.tv_nsec): XFAIL for

As noted in bug 17786, MIPS o32 struct stat has the wrong type of
st_dev. This patch XFAILs that test in the conformtest expectations
for this case (the test still fails after the patch because there's
also a similar issue for st_rdev that needs reporting and XFAILing
separately, and the bug should not be closed without an actual fix,
not just XFAILing).
Tested for mips with build-many-glibcs.py.
[BZ #17786]
* sysdeps/unix/sysv/linux/mips/mips32/Makefile: New file.
* conform/data/sys/stat.h-data (stat.st_dev): XFAIL for
mips-o32-linux.
This patch fixes various conformtest sys/stat.h expectations that were
incorrect for XPG3 (not based on a full review, so not necessarily an
exhaustive set of such corrections). Most of these corrections fix
spurious failures shown in testing (but that for fchmod introduces a
correct failure, as that function is wrongly declared for XPG3, so
this doesn't eliminate any XFAILs).
Tested for x86_64 and x86.
* conform/data/sys/stat.h-data [XPG3] (S_IFLNK): Do not expect.
[XPG3] (S_IFSOCK): Likewise.
[XPG3] (S_ISVTX): Likewise.

[XPG3] (S_ISSOCK): Likewise.
[XPG3] (fchmod): Likewise.
[XPG3] (lstat): Likewise.
[XPG3] (mknod): Likewise.
The conformtest expectations expect the struct stat fields st_blksize
and st_blocks to be of types blksize_t and blkcnt_t. But XPG4 does
not have those types, using long instead, and XPG3 does not have these
fields at all. This patch adjusts the expectations for those
standards, XFAILing them for XPG4 to allow for systems where the
typedefs don't correspond to long.
Tested for x86_64 and x86.
* conform/data/sys/stat.h-data (st_blksize): Do not expect for
[XPG3]. Expect type long and XFAIL for [XPG4].
(st_blocks): Likewise.

here is the patch with consistent __USE_XOPEN2K8
