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
