You could use --status-fd, which is locale-independent.

The environment variables are documented in the GNU C Library manual:

| Categories of Activities that Locales Affect
============================================| 
| 
|    The purposes that locales serve are grouped into "categories", so
| that a user or a program can choose the locale for each category
| independently.  Here is a table of categories; each name is both an
| environment variable that a user can set, and a macro name that you can
| use as an argument to `setlocale'.
| 
| `LC_COLLATE'
|      This category applies to collation of strings (functions `strcoll'
|      and `strxfrm'); see *Note Collation Functions::.
| 
| `LC_CTYPE'
|      This category applies to classification and conversion of
|      characters, and to multibyte and wide characters; see *Note
|      Character Handling::, and *Note Character Set Handling::.
| 
| `LC_MONETARY'
|      This category applies to formatting monetary values; see *Note
|      General Numeric::.
| 
| `LC_NUMERIC'
|      This category applies to formatting numeric values that are not
|      monetary; see *Note General Numeric::.
| 
| `LC_TIME'
|      This category applies to formatting date and time values; see
|      *Note Formatting Calendar Time::.
| 
| `LC_MESSAGES'
|      This category applies to selecting the language used in the user
|      interface for message translation (*note The Uniforum approach::;
|      *note Message catalogs a la X/Open::).
| 
| `LC_ALL'
|      This is not an environment variable; it is only a macro that you
|      can use with `setlocale' to set a single locale for all purposes.
|      Setting this environment variable overwrites all selections by the
|      other `LC_*' variables or `LANG'.
| 
| `LANG'
|      If this environment variable is defined, its value specifies the
|      locale to use for all purposes except as overridden by the
|      variables above.
| 
|    When developing the message translation functions it was felt that
| the functionality provided by the variables above is not sufficient.
| For example, it should be possible to specify more than one locale name.
| Take a Swedish user who better speaks German than English, and a program
| whose messages are output in English by default.  It should be possible
| to specify that the first choice of language is Swedish, the second
| German, and if this also fails to use English.  This is possible with
| the variable `LANGUAGE'.  For further description of this GNU extension
| see *Note Using gettextized software::.
