When applying this bug, I noticed that some of the changes were specified
in the wrong place. Since the stated intention was for the %b changes to be
"parallel" with those for %B, I have made the changes in the same places as
those in bug https://austingroupbugs.net/view.php?id=258.

Specifically:ab_alt_mon was added to time_keyword_opt, not to
time_keyword_name,

The new strftime and strptime conversion specifiers were added under the
Modified Conversion Specifiers heading instead of in with the "normal"
specifiers.
Also, the changes for the date utility were not needed, since bug
https://austingroupbugs.net/view.php?id=466
replaced the conversion specifiers list with a reference to strftime.

WG14 have agreed to include equivalent changes in C2X. Perhaps this should
be noted in "Future Directions"?

Interpretation response


The standard does not speak to this issue, and as such no conformance
distinction can be made between alternative implementations based on this.
This is being referred to the sponsor.

Rationale:
-
The locale specification is believed to be incomplete.

Notes to the Editor (not part of this interpretation):
---
Make the changes in the desired action, but with CX shading on the
strftime() addition. Also add CX shading to the strftime() addition from
bug http://austingroupbugs.net/view.php?id=258.

The text may be in the standard already somewhere, about defaulting for
other %O types and testing them. I added that to make sure it doesn't get
overlooked. Some may prefer they default to empty strings, rather than be
copies, as a design consideration too.

> rather than require existing locales to all add dummy settings for these

I didn't find a good place to add it to the spec, but what we are doing
about this in glibc is, our version of the localedef utility will set the
altmon/abaltmon strings equal to the mon/abmon strings if they aren't
specified in a definition file.

While a corner case, I agree for thoroughness this has merit. Additionally,
having %Od and %OD so both %b and %Ob forms, or respectively %B and %OB
with %D and %OD, may be accessible for the full date usages appears
warranted. A way to test whether alternate forms are present in an active
locale should also be documented for langinfo() for these specifiers,
rather than require existing locales to all add dummy settings for these.

Summary:Case variants needed for strftime %b as well as %B
Description: 
In the process of implementing the resolution to defect #258
 in the GNU C Library, we have
found that case variants are needed for abbreviated month names (%b) as
well as full month names (%B).  For example, in Russian the name of the
fifth month is май, which is only three letters, so it doesn't change
when abbreviated, and the abbreviation declines just like the full noun
(май nominative, мая genitive).
Desired Action: 
Make parallel changes for %b as were accepted for %B in #258.  Suggested
edits (these assume that the edits in #258 have already been applied):


Locale Sec 7.3.5.1 LC_TIME Locale Definition, at the end of the
specification of the "abmon" keyword, add: For languages having both a
genitive (when used with a day number) and a nominative (no day number)
case, this operand shall be used to denote the genitive case.

Locale Sec 7.3.5.1 LC_TIME Locale Definition, after the specification of
the "abmon" keyword, insert:
ab_alt_mon Define the abbreviated month names, corresponding to the %Ob
conversion specification. The operand shall consist of twelve
-separated strings, each surrounded by double-quotes. The first
string shall be the abbreviated name of the first month of the year
(January), the second the abbreviated name of the second month, and so on.
For languages having both a genitive (when used with a day number) and a
nominative (no day number) case, this operand shall be used to denote the
nominative case.

Locale Sec 7.3.5.2 LC_TIME C-Language Access, after the specification of
ABMON_x, insert:
ABALTMON_x The alternative abbreviated month names (for example, Jan),
where x is a number from 1 to 12.

Locale Sec 7.3.5.3 LC_TIME Category in the POSIX Locale, after the "abmon"
entries in the table, add these entries:
ab_alt_mon ABALTMON_1 %Ob N/A
ab_alt_mon ABALTMON_2 %Ob N/A
ab_alt_mon ABALTMON_3 %Ob N/A
ab_alt_mon ABALTMON_4 %Ob N/A
ab_alt_mon ABALTMON_5 %Ob N/A
ab_alt_mon ABALTMON_6 %Ob N/A
ab_alt_mon ABALTMON_7 %Ob N/A
ab_alt_mon ABALTMON_8 %Ob N/A
ab_alt_mon ABALTMON_9 %Ob N/A
ab_alt_mon ABALTMON_10 %Ob N/A
ab_alt_mon ABALTMON_11 %Ob N/A
ab_alt_mon ABALTMON_12 %Ob N/A

Locale Sec 7.4.2 Locale Grammar, to the "time_keyword_name" production
add:
| 'ab_alt_mon'

langinfo.h, in the table of symbolic constants with type nl_item, after
ABMON_12 add:
ABALTMON_1 LC_TIME Abbreviated alternative name of the first month of the
year.
ABALTMON_2 LC_TIME Abbreviated alternative name of the second month.
ABALTMON_3 LC_TIME Abbreviated alternative name of the third month.
ABALTMON_4 LC_TIME Abbreviated alternative name of the fourth month.
ABALTMON_5 LC_TIME Abbreviated alternative name of the fifth month.
ABALTMON_6 LC_TIME Abbreviated alternative name of the sixth month.
ABALTMON_7 LC_TIME Abbreviated alternative name of the seventh month.
ABALTMON_8 LC_TIME Abbreviated alternative name of the eighth month.
ABALTMON_9 LC_TIME Abbreviated alternative name of the ninth month.
ABALTMON_10 LC_TIME Abbreviated alternative name of the tenth month.
ABALTMON_11 LC_TIME Abbreviated alternative name of the eleventh month.
ABALTMON_12 LC_TIME Abbreviated alternative name of the twelfth month.

strftime, in the list of conversion specifiers, after 'b' insert
Ob   Replaced by the locale’s abbreviated alternative month name.

strptime, in the list of conversion specifiers, replace the definitions of
'b', 'B', and 'OB' with:
b   The month, using the locale's month names; either the abbreviated or
full version of either the default or the alternative month name may be
specified.
B   Equivalent to b.
Ob  Equivalent to b.
OB  Equivalent to b.

Also add immediately below 'h':
Oh  Equivalent to b.
