The below text is quoted from the latest POSIX draft:
: The values of locale categories shall be determined by a precedence
: order; the first condition met below determines the value:
:
: 1. If the LC_ALL environment variable is defined and is not null,
: the value of LC_ALL shall be used.
: 2. If the LC_* environment variable (LC_COLLATE, LC_CTYPE, LC_MESSAGES,
: LC_MONETARY, LC_NUMERIC, LC_TIME) is defined and is not null, the
: value of the environment variable shall be used to initialize the
: category that corresponds to the environment variable.
: 3. If the LANG environment variable is defined and is not null, the
: value of the LANG environment variable shall be used.
: 4. If the LANG environment variable is not set or is set to the empty
: string, the implementation-defined default locale shall be used.
The conditions 1 and 2 were interchanged, i.e., LC_* were looked first,
then LC_ALL, then LANG (note that LC_ALL and LANG were essentially the
same, providing the default, with LC_ALL taking precedence over LANG).
Now, LC_ALL and LANG serve the different purposes. LC_ALL overrides
any LC_*, and LANG provides the default fallback.
Testcase:
/usr/bin/env LC_ALL=C LC_TIME=de_DE.ISO_8859-1 /bin/date
Should return date in the "C" locale format.

lock definitions to it. flockfile state is now allocated
along with the rest of FILE. This eliminates the need for a
separate allocation of flockfile state as well as eliminating
the mutex/lock used to serialize its allocation.
Even better formula from random() could not be intetgrated because rand_r()
supposed to store its state in the single variable (but table needed for
random() algorithm integration).
- new EV_SET macro,
- NOTE_LOWAT option for low water marks on read/write filters,
- NOTE_REVOKE for filesystem unmounting (and revoke() calls)
- improved API for EVFILT_AIO
sysctls exporting swap information. When running on a live kernel,
the sysctl's will now be used instead of kvm_read, allowing consumers of
this interface to run without privilege (setgid kmem). Retain the
ability to run on coredumps, or on a kernel using kmem if explicitly
pointed at one.
A side effect of this change is that kvm_getswapinfo() is faster now in
the general case. If the SWIF_DUMP_TREE flag is given (pstat -ss does
this), the radix tree walker, which still uses kvm_read in any case, is
invoked, and therefore does require privilege.

This is about to be replaced anyway by initialization explicitly
instead of lazily, and reducing the complexity of it. As it is
now, this will work fine, however.
while with threaded software in -CURRENT acting very "weird". It has
seemed, for example, in Mozilla that threads attempting to do host
lookups have been locking up. That's exactly the case.
There was a race condition in the implementation of the initialization
of the mutex used to protect FILE operations, first of all: multiple
instances of FLOCKFILE() in libc could occur on the same FILE at
the same time and cause strange behavior by overwriting eachothers'
creation of the mutex and the rest of the file lock.
Secondly, it's not appropriate to test the "validity" of the file
descriptor referenced by the FILE; if the code is calling FLOCKFILE()
or FUNLOCKFILE(), it wants the FILE to be locked or unlocked, not
to be locked or unlocked on the condition that _file is >= 0. This
also could quite easily cause leaks by failing to perform the lock or
unlock operation when it actually is needed.
Mozilla now works again on -CURRENT when linked to libc_r.so.5 and
libc.so.5.
