Quoting POSIX:2001:
"All implementations shall define a locale as the default locale,
to be invoked when no environment variables are set, or set to the
empty string. This default locale can be the C locale or any other
implementation-defined locale. Some implementations may provide
facilities for local installation administrators to set the default
locale, customizing it for each location. IEEE Std 1003.1-2001 does
not require such a facility."
