strftime(3) for IEEE Std 1003.1-2001 compliance and remove
excessive usage of the 'const' qualifier that was neither
present in the prototype in the publice header, nor in the
local prototype just above the function definition.
- Replace the K&R function definition with a ANSI-C one.
- Update the prototype of strftime(3) in its manual page.
since they not allows POSIXly legal locale data. Currently, if relaxed form
POSIXly legal locale data will be used right now, some programs will be broken,
but it means that either locale data or programs must be fixed, not the library.
Introduce non-standard md_order (month/day order) locale field to be used later
via nl_langinfo(). Currently %EF and %Ef emulated using this field, but they
planned for remove in future in favour of nl_langinfo() test field.
Implement %F per POSIX
adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.
Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE. We have recursive mutexes, but would like to avoid
using them if possible.
Remove uneeded includes of <errno.h> from a few files.
Add $FreeBSD$ to a few files in order to pass commitprep.

strftime(3), add another one. :) %z yields the local timezone's offset
in hours and minutes, as used in RFC822 headers. There's a precedence
for this in Lunux' libc, and Internet software (like Perl scripts)
start using it.
OKed by (wrt. the code freeze): jkh
representation of the full month name. In the Russian locale, this alternative
will be "nominative case", useful when the date designate month as a whole.
E.g. month heading in a calendar. I hope it can be useful for some other
locales too.

Obtained from: partial merge of ADO version tzcode96h (was fully merged
in 1.10 but backed out in 1.11; the FreeBSD code for %s
was earlier, prettier but buggier).
modify the original `no modifications' copyright message, and i've
included his mail into the source file.
The common localization functions between strptime(3) and strftime(3)
have been broken out into timelocal.[ch].
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
part that does zic(8)/zdump(8) is still yet to be imported (but the old
zic and zdump will work just fine with these header files and the
data format has not changed).
by me). This probably loses for multibyte characters, but I have no
way of telling. I'll let ache decide whether to add this support to
startup_setlocale. Note that for this to make any sense at all, the
symlinks in /usr/share/locale must go. (For the moment, this doesn't
make any difference since there are no locales supplied.)

from the code in strftime.c . This affects both the library code
and all the commands using it (e.g. date +%s).
Note that %s is not required by ANSI, but we've already got it in 1.1.5.1.
