glibc does:
/* There should be no difference between the UTF-32 handling required
by c32rtomb and the wchar_t handling which has long since been
implemented in wcrtomb. */
weak_alias (__wcrtomb, c32rtomb)
/* There should be no difference between the UTF-32 handling required
by mbrtoc32 and the wchar_t handling which has long since been
implemented in mbrtowc. */
weak_alias (__mbrtowc, mbrtoc32)
The reasoning in those comments to justify those aliases is incorrect:
ISO C requires that, for the case of a NULL mbstate_t* being passed,
each function has its *own* internal static mbstate_t. Thus a program
must be able to use both wcrtomb and c32rtomb at the same time with
each keeping its own separate state, and likewise for mbrtowc and
mbrtoc32.
This patch duly sets up separarate char32_t function that wrap the
wchar_t ones. Note that the included test only covers the mbrtoc32 /
mbrtowc pair. While I think the change made is logically correct for
c32rtomb / wcrtomb as well, I'm not sure we have a locale with a
suitable state-dependent multibyte encoding for testing that part of
the change.

The c16rtomb implementation has:
// XXX The ISO C 11 spec I have does not say anything about handling
// XXX surrogates in this interface.
The DR#488 resolution, as applied to C2X, requires surrogate pairs to
be handled here (so the first call returns 0 and stores the high
surrogate in the mbstate_t, while the second call combines the
surrogates, produces a multibyte character and returns the number of
bytes written). This patch implements that. (mbrtoc16 already
handled producing surrogates as output.)

C99 specifies that the EOF condition on a file is "sticky": once EOF
has been encountered, all subsequent reads should continue to return
EOF until the file is closed or something clears the "end-of-file
indicator" (e.g. fseek, clearerr). This is arguably a change from
C89, where the wording was ambiguous; the BSDs always had sticky EOF,
but the System V lineage would attempt to read from the underlying fd
again. GNU libc has followed System V for as long as we've been
using libio, but nowadays C99 conformance and BSD compatibility are
more important than System V compatibility.
You might wonder if changing the _underflow impls is sufficient to
apply the C99 semantics to all of the many stdio functions that
perform input. It should be enough to cover all paths to _IO_SYSREAD,
and the only other functions that call _IO_SYSREAD are the _seekoff
impls, which is OK because seeking clears EOF, and the _xsgetn impls,
which, as far as I can tell, are unused within glibc.
The test programs in this patch use a pseudoterminal to set up the
necessary conditions. To facilitate this I added a new test-support
function that sets up a pair of pty file descriptors for you; it's
almost the same as BSD openpty, the only differences are that it
allocates the optionally-returned tty pathname with malloc, and that
it crashes if anything goes wrong.

As noted in bug 17979 (and as I noted earlier in
<https://sourceware.org/ml/libc-alpha/2012-02/msg00647.html>), uchar.h
has gratuitously complicated code to determine the types for char16_t
and char32_t, and to reject including that header for pre-C11
compilers not defining __CHAR16_TYPE__ and __CHAR32_TYPE__. Since
those types are always required to match uint_least16_t and
uint_least32_t, which glibc knows how to define without reference to
such predefined macros, it's safe just to define those types the same
as the *least* types are defined in stdint.h, so allowing the header
to work with (for example) GCC 4.3.
This patch implements that. bits/types.h is made to define
__int_leastN_t and __uint_leastN_t so the logic for those types can
stay in a single place, and stdint.h is made to use those __*_t to
define the public *_t types. uchar.h is then made to use
__uint_least16_t and __uint_least32_t to define char16_t and char32_t,
so simplifying the logic there. A new test is added that verifies the
types chosen for char16_t and char32_t do indeed match the types the
compiler uses for u"" and U"" string literals.
Tested for x86_64. (I have not tested with any of the older compilers
for which this would actually make a difference to whether you can
include uchar.h.)

This extends tst-strtod-round with a few trivial changes
to also test the wide character variants of strto* using
similar macros to other shared tests.
The nan* functions handle their string argument by constructing a
NAN(...) string on the stack as a VLA and passing it to strtod
functions.
This approach has problems discussed in bug 16961 and bug 16962: the
stack usage is unbounded, and it gives incorrect results in certain
cases where the argument is not a valid n-char-sequence.
The natural fix for both issues is to refactor the NaN payload parsing
out of strtod into a separate function that the nan* functions can
call directly, so that no temporary string needs constructing on the
stack at all. This patch does that refactoring in preparation for
fixing those bugs (but without actually using the new functions from
nan* - which will also require exporting them from libc at version
GLIBC_PRIVATE). This patch is not intended to change any user-visible
behavior, so no tests are added (fixes for the above bugs will of
course add tests for them).
This patch builds on my recent fixes for strtol and strtod issues in
Turkish locales. Given those fixes, the parsing of NaN payloads is
locale-independent; thus, the new functions do not need to take a
locale_t argument.

The implementations of strtod and related functions use
locale-specific conversions to lower case when parsing the contents of
a string NAN(n-char-sequence_opt). This has the consequence that
NAN(I) is not treated as being of that form (only the initial NAN part
is accepted). The syntax of n-char-sequence directly maps to the
ASCII letters, digits and underscore as in identifiers, so it is
unambiguous that all ASCII letters must be accepted in all locales.
This patch, relative to a tree with
<https://sourceware.org/ml/libc-alpha/2015-11/msg00258.html> (pending
review) applied and depending on that patch, fixes this problem by
checking directly for ASCII letters. This will have the side effect
of no longer accepting 'İ' (dotted 'I') inside NAN() in Turkish
locales, which seems appropriate (that letter wouldn't have been
interpreted as having any meaning in the NaN payload anyway, as not
acceptable to strtoull).
Tested for x86_64 and x86.

The implementations of strtol and related functions use
locale-specific conversions to upper case before determining whether a
character is a valid letter in the argument. This means that in
Turkish locales such as tr_TR.UTF-8 and tr_TR.ISO-8859-9, "i" is
interpreted as not being a valid number, when if the base passed to
strtol is 19 or more it should be interpreted as the number 18.
ISO C explicitly says "The letters from a (or A) through z (or Z) are
ascribed the values 10 through 35", so clearly intends the standard
ASCII letters (otherwise you wouldn't generally have exactly 26
letters to ascribe such values) (whereas white-space must be
identified according to the locale). In particular, 'i' and 'I' must
be understood to be in that sequence.
This patch makes the code do the case conversions and classification
in the C locale; the user's locale remains used for whitespace testing
(explicitly correct according to ISO C). Note that the way the code
worked, the only non-ASCII letter that would previously have been
accepted would have been the Turkish 'ı' (dotless 'i'), because the
uppercase version of that in Turkish locales is 'I'. This patch means
that will no longer be accepted, which seems appropriate.

TEST_IFUNC is only tested in two headers, bench-string.h and

just define TEST_IFUNC and include other tests are also redundant, as
is the code to remove $(tests-ifunc) and $(xtests-ifunc) conditionally
from tests and xtests. This patch removes the useless defines and
tests of TEST_IFUNC and the associated useless tests and makefile
code. It thereby fixes a series of warnings
"../string/test-string.h:21:0: warning: "TEST_IFUNC" redefined" where
test-string.h defines TEST_IFUNC to empty, other files define it to 1

Tests run using the default $(make-test-out) automatically get
GCONV_PATH and LC_ALL set, whether or not those environment variables
are actually needed for the individual test. However, they do not get
LOCPATH set, meaning that a large number of tests have -ENV settings
just to set LOCPATH.
This patch moves LOCPATH into the default environment used for all
tests, on the principle that like GCONV_PATH any settings needed to
use files associated with the newly built library, rather than any old
installed files, are appropriate to use by default.
A further motivation is that various tests using .sh files also set
some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh
files should also use the default environment with any additions
required for the individual test. Now, it was suggested in
<https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that
various Makefile variables used in testing should be derived by
composing the -before-env and -after-env variables used when explicit
environment settings are required. With such a change, it's also
natural for those variables to include the default settings (via some
intermediate makefile variable also used in make-test-out).
Because some .sh files only set variables that correspond to the
default settings, or a subset thereof, and this applies to more of the
.sh files once LOCPATH is in the default settings, doing so reduces
the size of a revised version of
<https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts
only needing the (expanded) default settings will not need to receive
the separate -before-env and -after-env variables, only the single
variable they do at present. So moving LOCPATH into the default
settings can reduce churn caused by subsequent patches.

In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information. No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.
This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules). Includes are added if needed, or moved up if already
present. Subdirectory "all:" targets are removed, since Makeconfig
provides one.
There is potential for further cleanups I haven't done. Rules and
Makerules have code such as
ifneq "$(findstring env,$(origin headers))" ""
headers :=
endif
to override to empty any value of various variables that came from the
environment. I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable. (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.) Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves. The special code to override values coming
from the environment would then be obsolete and could be removed.
Tested x86_64, including that installed binaries are identical before
and after the patch.

The -D_FORTIFY_SOURCE flags are being added to the test-specific CFLAGS
values when they should be the test-specific CPPFLAGS values. Otherwise
the values don't override the user-specified CPPFLAGS and might end up
breaking the tests.

It isn't necessary to buffer the last character of strings. This can cause a
bug with strings that have 1 character between 0x0041 and 0x01b0.
[BZ #13691]
* iconvdata/tcvn5712-1.c (FROM_LOOP): Fix a bug when converting strings
with only 1 character between 0x0041 and 0x01b0.
* wcsmbs/Makefile (tests): Add tst-mbsnrtowcs.
* wcsmbs/tst-mbsnrtowcs.c: New file.
