/**
    @class wxXLocale

    This class represents a locale object used by so-called xlocale API.

    Unlike wxLocale it doesn't provide any non-trivial operations but simply
    provides a portable wrapper for POSIX @c locale_t type.

    It exists solely to be provided as an argument to various @c wxFoo_l() functions
    which are the extensions of the standard locale-dependent functions (hence the
    name xlocale). These functions do exactly the same thing as the corresponding
    standard @c foo() except that instead of using the global program locale
    they use the provided wxXLocale object.

    See @ref group_funcmacro_locale for a list of wxXLocale-enabled functions.

    Conversely, if a program wanted to output the number in French locale, even if
    the current locale is different, it could use wxXLocale(wxLANGUAGE_FRENCH).


    @section xlocale_avail Availability

    This class is fully implemented only under the platforms where xlocale POSIX
    API or equivalent is available. Currently the xlocale API is available under
    most of the recent Unix systems (including Linux, various BSD and Mac OS X) and
    Microsoft Visual C++ standard library provides a similar API starting from
    version 8 (Visual Studio 2005).

    If neither POSIX API nor Microsoft proprietary equivalent are available, this
    class is still available but works in degraded mode: the only supported locale
    is the C one and attempts to create wxXLocale object for any other locale will
    fail. You can use the preprocessor macro @c wxHAS_XLOCALE_SUPPORT to test if
    full xlocale API is available or only skeleton C locale support is present.

    Notice that wxXLocale is new in wxWidgets 2.9.0 and is not compiled in if
    @c wxUSE_XLOCALE was set to 0 during the library compilation.
