Could we pretty please have a different notation for this?

Languages that do have different nominative and genitive forms might also want to have lowercase and uppercase variants (for both kinds), why not allow it for them too? 

If the same syntax is overloaded, how could any piece of software safely decide whether to use %B or %OB (or: %b or %Ob) and be sure that it's going to be okay? You'd need to pick one based on the characteristics of the language, based on the meaning of the "O" modifier for that particular language, which is practically a no-go.

Plus, by the way, lowercase/uppercase variants might be relevant for the AM/PM strings as well.

Different semantics should be achieved using a different syntax.

Thanks!

I absolutely agree.  This idea is already reflected in these bug reports:

* bug 21370: introduce a "convert to titlecase" flag;
* bug 15527: make the combination of existing flags "^#" work correctly and convert to lowercase;
* optionally: specify that all locale data must be titlecased and convert them to all uppercase/all lowercase only on an explicit demand.

Providing the upper/lowercase variant would be meant only as a workaround or a temporary solution; also it is suggested by CLDR as a good use of the software feature which is actually used by only a minority of languages.

This applies to Scottish Gaelic indeed (gd-GB) but they're not genitives though, they're partitives - and I think other languages will be using other grammatical patterns too, so perhaps the naming should be more general, like "inflected month name" rather than genitive?

Anyway, starting with January, the inflected forms are as follows:

dhen Fhaoilleach
dhen Ghearran
dhen Mhàrt
dhen Ghiblean
dhen Chèitean
dhen Ògmhios
dhen Iuchar
dhen Lùnastal
dhen t-Sultain
dhen Dàmhair
dhen t-Samhain
dhen Dùbhlachd

Upper Sorbian:

Nominative             Accusative                Genitive

januar                 januar                    januara
februar                februar                   februar
měrc                   měrc                      měrca
apryl                  apryl                     apryla
meja                   meju                      meje
junij                  junij                     junija
julij                  julij                     julija
awgust                 awgust                    awgusta
september              september                 septembra
oktober                oktober                   oktobra
nowember               nowember                  nowembra
december               december                  decembra

Meja "May" is an exceptional case: It is the only month name that has feminine gender. Therefore its nominative and accusative are not identical. Besides it has the ending -e in genitive instead of -a. With the month names for september, oktober, nowember and december, the vowel "e" is elided before the consonant "r".

Lower Sorbian:

Nominative             Accusative                Genitive

januar                 januar                    januara
februar                februar                   februar
měrc                   měrc                      měrca
apryl                  apryl                     apryla
maj                    maj                       maja
junij                  junij                     junija
julij                  julij                     julija
awgust                 awgust                    awgusta
september              september                 septembra
oktober                oktober                   oktobra
nowember               nowember                  nowembra
december               december                  decembra

The most Lower Sorbian month names are identical to the Upper Sorbian ones with one exception: maj "May". Maj is masculine and therefore nominative and accusative are identical here. The Upper Sorbian exceptional case does not exist in Lower Sorbian.

There is a fourth grammatical case that often occurs: The locative. It mainly occurs behind the preposition w "in":

w januarje "in January"
w februarje "in February"
w měrcu "in March"
w aprylu "in April"
w meji (Upper Sorbian), w maju (Lower Sorbian) "in May"
w juniju "in June"
w juliju "in July"
w awgusće "in August"
w septembrje "in September"
w oktobrje "in October"
w nowembrje "in November"
w decembrje "in December"

Sorry, a typo: The genitive of "februar" must be "februara", of course, both for Upper Sorbian and Lower Sorbian.

Thank you for this update. The documentation never uses the term "genitive" nor "nominative". I often use the term "genitive" because: (1) it is shorter than "a  form used when the month name forms part of the date"; (2) so far I have not known about any language which requires other case than genitive; (3) a genitive case is a good example of a form required to format a date.

Thank you. This is already provided by CLDR and I have patches ready for Scottish Gaelic and several other languages as well. I am going to attach them in the beginning of the next week. I will appreciate a final review, though.

Thank you. Unfortunately, we are unable to support more than 2 cases. This is a minimum required to format a date. I guess that the correct case for Upper Sorbian when formatting a date is genitive. Supporting more cases is a task for a natural language translating and processing tool, not for strftime() function from glibc. Again, I have a patch for the Upper Sorbian and I am going to attach it next week.

That's very interesting, thank you.

OK, I am familiar with these phenomenons because they are the same in my native language.

As I said above, Lower Sorbian is not supported by glibc. I'll be happy to add it, though, especially since I see it supported by CLDR. Can you please open a separate ticket and (even better) provide a patch? If you can't then tell me so I will do it but I will need an assistance to complete the task.

As I said above, we can't support more than two cases. This would be useful to generate natural language sentences and maybe in some more applications but it is not absolutely necessary for strftime() function to display dates correctly.

Hi Rafał,

thank you for your reply.

Well, you are right, Sorbian languages use the month names in genitive in dates if the day is specified:

Dźensa je 05. meje 2018. (Upper Sorbian)
Źinsa jo 05. maja 2018. (Lower Sorbian)
Today is 5th May, 2018.

Locative is always used with prepositions. There would be a problem only if month name placeholders are used because placeholders cannot be inflected. Strftime() uses such placeholders: %d. %B %Y. %B cannot be inflected so "w %B" would result in "w meja" instead in correct "w meji". 

Another problem would occur if any software is intended to use the OS locale for date and time. There is no operating system in Sorbian languages until now. That's a problem of many minority languages.

OK, count them as about to be supported.

True, this is not supported. But please note that this is a sentence, or almost a sentence rather than just a date. This does not work in any inflected language. We need a place where we say "this is too complex for glibc, please use a translation software or an AI instead". :-)

You are just invited to create one. :-) Really not much is left to do. In fact, HSB has been supported in glibc for a long time now except this bug with a correct grammar of dates.

Shouldn't the genitive case be "februara"?

And the same in Lower Sorbian.

Asturian (ast_ES)

Here I include a set of patches for easier review by the respective language teams. I think that eventually all (or almost all) of these patches will be squashed and pushed together unless we get a negative feedback. I'd like to push them in a month. Also they can be pushed individually earlier if a language team wishes. Unfortunately, I suspect that for some of these languages it will be difficult to reach actual translators.

Finnish (fi_FI)

I think we have sufficient negative feedback for this language (i.e., the native speakers don't want this change) but here I attach it for the last chance in case they change their minds. The reason is that the inflection rule in Finnish language is simple: append "ta" at the end of every month name and we get a correct genitive case. This is a currently used workaround.

Scottish Gaelic (gd_GB)

I think we have a sufficient positive feedback and a very responsive language team. If you wish the patch to be committed now and reach the prerelease distros (like Fedora Rawhide) then please say. Otherwise it will be committed in a month.

Slovak (sk_SK)

This change is controversial (same as Czech and Serbian) because, as far as I understand the grammar rules, while a genitive case of a month name is sometimes required the normal date format is day_number + ". " + month_name_nominative. I will not commit without a positive feedback from the language team. However, I hope the change will be useful and I offer my help when adopting it.

Grammar is correct, but it would be better to capitalize alt_mon strings too for consistency.

Lower Sorbian can be ignored by this bug now. Meanwhile bug 23208 exists with the complete new locale file dsb_DE which already contains the genitive month names for dates.

Thank you for your review. alt_mon is currently capitalized in this patch. Did you mean anything different?

BTW, what do you think about abbreviated month names? Currently in glibc we have all Ossetian month names abbreviated to 3 letters. CLDR [1] provides 3-4 letters plus a dot unless whole word is 3 or 4 letters long. As a consequence some "abbreviated" month names have their inflection visible: "Май" -> "майы", "Июнь" -> "июны" and so on. Also, the abbreviated standalone (nominative?) forms are all capitalized.

[1] http://st.unicode.org/cldr-apps/v#/os/Gregorian/

While at this, what is the correct English name: Ossetian (Wikipedia says so) or Ossetic (CLDR says so)?

I think consistency is more important. If other locales in glibc use 3 letter abbreviations then Ossetian locale should use 3 letters too. As for usability, both styles are equally recognizable.

Both are correct, but IMO Ossetian is more modern.

That's not the case, see e.g. bug 192 and bug 22848. IMO use whichever is grammatically correct / better / more typically used etc. in the given language.

IMHO as we are speaking about POSIX locales, so we should use POSIX style names, that
is, oriented towards POSIX utilities use. CLDR is not oriented towards POSIX use.

Actually we should also allow for more grammatically oriented names.
But that should be new functionality, using new keywords. In that way we will
have POSIX functionality which is still functional

And I am still uncertain that what glibc is doing now is following the POSIX standard.
POSIX has recently (within the last couple of years) adressed the genitive month names problem,
in a way compatible with BSD. I have not yet gotten around to verifying that glibc is
following POSIX here.

Locale data should follow the grammar rules of respective languages.  Are there rules in Ossetian which say that the month name should always be capitalized, like in English, German and few more languages?  This page: https://os.wikipedia.org/wiki/26_%D0%BC%D0%B0%D0%B9%D1%8B says "26 майы" which is lowercase.  If this is correct then mon should be lowercase, same as CLDR provides.  Uppercasing alt_mon is not obligatory but both glibc and CLDR provide so and I will not change it without need.

There is no requirement that they should be 3 letters.  Some languages follow that rule, some do not.  But if this is recognizable then I will not change it unless you request.

I don't remember where I read this but someone wrote that those POSIX rules apply to English language, not to other languages.  POSIX authors are not aware of every language in the world, therefore the rules are occasionally amended to support more languages.

If you mean the bug 10871 then in a part which refers to the full month names it strictly follows the rules of BSD, also follows the update which has been accepted by POSIX in 2010 but not yet published.  Therefore until it is published we call it "GNU extension" rather than "POSIX compatible".

Regarding the part which refers to the abbreviated month names the rules are similar but nobody except glibc so far implemented or proposed it.  POSIX has been asked to accept this as part of their standard but it may take another 10 years.  For now we call it a genuine GNU extension. :-)

Well,I have been around with POSIX locales for a long time, more than 25 years, and the
locales were always meant to be it support anything else than English.
So many other languages have these rules. POSIX authors at that time, including myself,
were quite aware of the requirements for many languages - but not for all.
This is still the case, POSIX i18n authors don't know everything in the world, but we are getting better.

I agree that POSIX may be slow sometimes. As said, it is my plan to check up on this.

I appreciate your work.  I did not mean you are totally unaware but not aware of every language because this is impossible.  In this context we are discussing Ossetian language.

Armenian (hy_AM)

I've found this in my computer and I think it is worth attention.  However, I can't read Armenian script.  Thoughts?

Here is a decoded version:

I can't even read Armenian script but I'm trying to figure out what's going on here.  Armenian alphabet seems to have upper and lowercase, same as Latin, Cyrillic, and Greek.  Glibc currently seems to provide the month names starting with uppercase.  It is easy to convert between uppercase and lowercase: uppercase code points are 0x30 less than lowercase.  For example, current March:

"<U0544><U0561><U0580><U057F><U056B>"

Decoded:

"Մարտի"

Should be transliterated as:

"Marti"

My patch which is an import from CLDR converts it to:

alt_mon: "<U0574><U0561><U0580><U057F>"        => "մարտ"  => "mart"
mon:     "<U0574><U0561><U0580><U057F><U056B>" => "մարտի" => "marti"

So it looks like the locale data currently contain the month names in a genitive case (or whatever is correct to use in a full date) starting with uppercase while CLDR uses lowercase exclusively.  Please note that we had a similar case in Lithuanian language already.

But Armenian language seems to use "month day" order, same as English, so the month name may tend to appear at the beginning of a sentence and it may be reasonable to start it with an uppercase even if there is no rule in a language which says that the month names should be always titlecased.  If mon array is titlecased then alt_mon should be as well (CLDR suggest that alt_mon may be titlecased and mon lowercased but not the reverse) so maybe we should use a titlecase for alt_mon as well.

Converting this to a titlecase the decoded patch for hy_AM would look like this:

https://hy.wikipedia.org/wiki/%D5%84%D5%A1%D6%80%D5%BF%D5%AB_1 (this is an example of an Armenian date)

If month (and day) names are not capitalized, then the should not be capitalized in our
locales, even if they often appear first in a sentence. This is damaging the culture in question.
I see a lot of instances in my own language, where people wrongly spell month (and day) names
with a capitalized first letter, and that is really not correct. Using the argumentation
below is not helping the language.

I think we are repeating the discussion from comment 2 and comment 3.  In short terms: it would be nice to have flags allowing to select uppercase/lowercase/titlecase but such feature does not exist yet.

I think I understand you.  But we can't fix the people wrongly spelling the month names (capitalizing where it is not correct), we can only fix software here (e.g., not capitalizing where it should).

Regarding the particular case of Armenian language I would like to leave the decision to the actual language community but I'm afraid that the community will not speak up here.  As we are not sure what to do and none of us has a sufficient knowledge I suggest not touching this language at all.

Kashubian (csb_PL) version 3

It seems that Kashubian language also needs the ab_alt_mon feature.

    csb_PL: Add alternative month names (bug 23140).
    
    Kashubian language is not supported by CLDR, data copied from Wikipedia
    and documents released by RJK (official Kashubian Language Council),
    also consulted with a native speaker.
    
    Note that this language also needs ab_alt_mon feature due to the month
    May: nominative "môj", genitive "maja"; abbreviated nominative "môj",
    abbreviated genitive "maj".

OK, good news: I have managed to contact an Armenian native speaker and he agrees that the month names should be lowercased.  This convinces me and I will proceed with the patch.

Good. You are of cause rigth in saying that we do not have a way to capitalize such
names. But then let us make a way to do it. My thoughts are to make some 
format specifier to change the first character til uppercase, both for
month and day names, and their abbreviations. I don't have a specific
proposal - but maybe a + somewhere could  do it. What do you think?

Fixed all I was able to fix.  Here is what remains not fixed:

* Finnish: I think it would be good but the existing workaround seems to be sufficient for the actual native speakers.
* Slovak: I would like to consult the actual native community because their rules of nominative/genitive cases seem to be different than in other languages.
* Serbian: the same as in Slovak + I don't have a reliable list of translated month names.
* Silesian: definitely needs an update but I don't have a reliable list of month names.

The GNU C Library
=================

The GNU C Library version 2.28 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.28 release may be downloaded from:
        http://ftpmirror.gnu.org/libc/
        http://ftp.gnu.org/gnu/libc/

The mirror list is at http://www.gnu.org/order/ftp.html

NEWS for version 2.28
=====================

Major new features:

* The localization data for ISO 14651 is updated to match the 2016
  Edition 4 release of the standard, this matches data provided by
  Unicode 9.0.0.  This update introduces significant improvements to the
  collation of Unicode characters.  This release deviates slightly from
  the standard in that the collation element ordering for lowercase and
  uppercase LATIN script characters is adjusted to ensure that regular
  expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
  is not matched by [a-z].  With the update many locales have been
  updated to take advantage of the new collation information.  The new
  collation information has increased the size of the compiled locale
  archive or binary locales.

* The GNU C Library can now be compiled with support for Intel CET, AKA
  Intel Control-flow Enforcement Technology.  When the library is built
  with --enable-cet, the resulting glibc is protected with indirect
  branch tracking (IBT) and shadow stack (SHSTK).  CET-enabled glibc is
  compatible with all existing executables and shared libraries.  This
  feature is currently supported on i386, x86_64 and x32 with GCC 8 and
  binutils 2.29 or later.  Note that CET-enabled glibc requires CPUs
  capable of multi-byte NOPs, like x86-64 processors as well as Intel
  Pentium Pro or newer.  NOTE: --enable-cet has been tested for i686,
  x86_64 and x32 on non-CET processors.  --enable-cet has been tested
  for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
  validated for i686.

* The GNU C Library now has correct support for ABSOLUTE symbols
  (SHN_ABS-relative symbols).  Previously such ABSOLUTE symbols were
  relocated incorrectly or in some cases discarded.  The GNU linker can
  make use of the newer semantics, but it must communicate it to the
  dynamic loader by setting the ELF file's identification (EI_ABIVERSION
  field) to indicate such support is required.

* Unicode 11.0.0 Support: Character encoding, character type info, and
  transliteration tables are all updated to Unicode 11.0.0, using
  generator scripts contributed by Mike FABIAN (Red Hat).

* <math.h> functions that round their results to a narrower type are added
  from TS 18661-1:2014 and TS 18661-3:2015:

  - fadd, faddl, daddl and corresponding fMaddfN, fMaddfNx, fMxaddfN and
    fMxaddfNx functions.

  - fsub, fsubl, dsubl and corresponding fMsubfN, fMsubfNx, fMxsubfN and
    fMxsubfNx functions.

  - fmul, fmull, dmull and corresponding fMmulfN, fMmulfNx, fMxmulfN and
    fMxmulfNx functions.

  - fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and
    fMxdivfNx functions.

* Two grammatical forms of month names are now supported for the following
  languages: Armenian, Asturian, Catalan, Czech, Kashubian, Occitan, Ossetian,
  Scottish Gaelic, Upper Sorbian, and Walloon.  The following languages now
  support two grammatical forms in abbreviated month names: Catalan, Greek,
  and Kashubian.

* Newly added locales: Lower Sorbian (dsb_DE) and Yakut (sah_RU) also
  include the support for two grammatical forms of month names.

* Building and running on GNU/Hurd systems now works without out-of-tree
  patches.

* The renameat2 function has been added, a variant of the renameat function
  which has a flags argument.  If the flags are zero, the renameat2 function
  acts like renameat.  If the flag is not zero and there is no kernel
  support for renameat2, the function will fail with an errno value of
  EINVAL.  This is different from the existing gnulib function renameatu,
  which performs a plain rename operation in case of a RENAME_NOREPLACE
  flags and a non-existing destination (and therefore has a race condition
  that can clobber the destination inadvertently).

* The statx function has been added, a variant of the fstatat64
  function with an additional flags argument.  If there is no direct
  kernel support for statx, glibc provides basic stat support based on
  the fstatat64 function.

* IDN domain names in getaddrinfo and getnameinfo now use the system libidn2
  library if installed.  libidn2 version 2.0.5 or later is recommended.  If
  libidn2 is not available, internationalized domain names are not encoded
  or decoded even if the AI_IDN or NI_IDN flags are passed to getaddrinfo or
  getnameinfo.  (getaddrinfo calls with non-ASCII names and AI_IDN will fail
  with an encoding error.)  Flags which used to change the IDN encoding and
  decoding behavior (AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES,
  NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES) have been
  deprecated.  They no longer have any effect.

* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
  DT_AUXILIARY, and DT_FILTER has been expanded to support the full
  range of ELF gABI expressions including such constructs as
  '$ORIGIN$ORIGIN' (if valid).  For SUID/GUID applications the rules
  have been further restricted, and where in the past a dynamic string
  token sequence may have been interpreted as a literal string it will
  now cause a load failure.  These load failures were always considered
  unspecified behaviour from the perspective of the dynamic loader, and
  for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
  results in a load failure now.

* Support for ISO C threads (ISO/IEC 9899:2011) has been added.  The
  implementation includes all the standard functions provided by
  <threads.h>:

  - thrd_current, thrd_equal, thrd_sleep, thrd_yield, thrd_create,
    thrd_detach, thrd_exit, and thrd_join for thread management.

  - mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, and
    mtx_destroy for mutual exclusion.

  - call_once for function call synchronization.

  - cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, and
    cnd_wait for conditional variables.

  - tss_create, tss_delete, tss_get, and tss_set for thread-local storage.

  Application developers must link against libpthread to use ISO C threads.

Deprecated and removed features, and other changes affecting compatibility:

* The nonstandard header files <libio.h> and <_G_config.h> are no longer
  installed.  Software that was using either header should be updated to
  use standard <stdio.h> interfaces instead.

* The stdio functions 'getc' and 'putc' are no longer defined as macros.
  This was never required by the C standard, and the macros just expanded
  to call alternative names for the same functions.  If you hoped getc and
  putc would provide performance improvements over fgetc and fputc, instead
  investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
  necessary, flockfile and funlockfile.

* All stdio functions now treat end-of-file as a sticky condition.  If you
  read from a file until EOF, and then the file is enlarged by another
  process, you must call clearerr or another function with the same effect
  (e.g. fseek, rewind) before you can read the additional data.  This
  corrects a longstanding C99 conformance bug.  It is most likely to affect
  programs that use stdio to read interactive input from a terminal.
  (Bug #1190.)

* The macros 'major', 'minor', and 'makedev' are now only available from
  the header <sys/sysmacros.h>; not from <sys/types.h> or various other
  headers that happen to include <sys/types.h>.  These macros are rarely
  used, not part of POSIX nor XSI, and their names frequently collide with
  user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
  further explanation.

  <sys/sysmacros.h> is a GNU extension.  Portable programs that require
  these macros should first include <sys/types.h>, and then include
  <sys/sysmacros.h> if __GNU_LIBRARY__ is defined.

* The tilegx*-*-linux-gnu configurations are no longer supported.

* The obsolete function ustat is no longer available to newly linked
  binaries; the headers <ustat.h> and <sys/ustat.h> have been removed.  This
  function has been deprecated in favor of fstatfs and statfs.

* The obsolete function nfsservctl is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and could not usefully be used with the GNU C Library on systems with
  version 3.1 or later of the Linux kernel.

* The obsolete function name llseek is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and was not declared in a header.  Programs should use the lseek64 name
  for this function instead.

* The AI_IDN_ALLOW_UNASSIGNED and NI_IDN_ALLOW_UNASSIGNED flags for the
  getaddrinfo and getnameinfo functions have been deprecated.  The behavior
  previously selected by them is now always enabled.

* The AI_IDN_USE_STD3_ASCII_RULES and NI_IDN_USE_STD3_ASCII_RULES flags for
  the getaddrinfo and getnameinfo functions have been deprecated.  The STD3
  restriction (rejecting '_' in host names, among other things) has been
  removed, for increased compatibility with non-IDN name resolution.

* The fcntl function now have a Long File Support variant named fcntl64.  It
  is added to fix some Linux Open File Description (OFD) locks usage on non
  LFS mode.  As for others *64 functions, fcntl64 semantics are analogous with
  fcntl and LFS support is handled transparently.  Also for Linux, the OFD
  locks act as a cancellation entrypoint.

* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
  ecb_crypt, and des_setparity are no longer available to newly linked
  binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
  longer installed.  These functions encrypted and decrypted data with the
  DES block cipher, which is no longer considered secure.  Software that
  still uses these functions should switch to a modern cryptography library,
  such as libgcrypt.

* Reflecting the removal of the encrypt and setkey functions above, the
  macro _XOPEN_CRYPT is no longer defined.  As a consequence, the crypt
  function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is
  enabled.

* The obsolete function fcrypt is no longer available to newly linked
  binaries.  It was just another name for the standard function crypt,
  and it has not appeared in any header file in many years.

* We have tentative plans to hand off maintenance of the passphrase-hashing
  library, libcrypt, to a separate development project that will, we hope,
  keep up better with new passphrase-hashing algorithms.  We will continue
  to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
  'crypt_r' should not need to change at all; however, distributions will
  need to install <crypt.h> and libcrypt from a separate project.

  In this release, if the configure option --disable-crypt is used, glibc
  will not install <crypt.h> or libcrypt, making room for the separate
  project's versions of these files.  The plan is to make this the default
  behavior in a future release.

  GNU make 4.0 or later is now required to build glibc.
