* variables, and setting them won't affect the behaviour of functions
* like ctime(). The user sets the locale through the Regional Options
* in the Control Panel. The C library (in the setlocale() function)
* does not use country and language codes, but country and language
* names spelled out in English.
* However, this function does check the above environment
* variables, and does return a Unix-style locale string based on
* either said environment variables or the thread's current locale.
*
* Return value: a dynamically allocated string, free with g_free().
