+
+ A large part of the code here deals with emulating glibc's reentrant
+ locale API on non-GNU systems. The emulation is a bit "brute-force":
+ Whenever a `-locale<?' procedure is passed a locale object, then:
+
+ 1. The `scm_i_locale_mutex' is locked.
+ 2. A series of `setlocale ()' call is performed to store the current
+ locale for each category in an `scm_t_locale' object.
+ 3. A series of `setlocale ()' call is made to install each of the locale
+ categories of each of the base locales of each locale object,
+ recursively, starting from the last locale object of the chain.
+ 4. The settings captured in step (2) are restored.
+ 5. The `scm_i_locale_mutex' is released.
+
+ Hopefully, the X/Open standard will eventually make this hack useless.
+
+ Note: We don't wrap glibc's `uselocale ()' call because it sets the locale
+ of the current _thread_ (unlike `setlocale ()') and doing so would require
+ maintaining per-thread locale information on non-GNU systems and always

+ normalization.
+
+ 2. `nl_langinfo ()' is not available on Windows.
+
+ 3. `nl_langinfo ()' may return strings encoded in a locale different from
+ the current one.
+ For example:
+
+ (nl-langinfo DAY_1 (make-locale LC_ALL "eo_EO.UTF-8"))
+
+ returns a result that is a UTF-8 string, regardless of the
+ setting of the current locale. If nl_langinfo supports CODESET,
+ we can convert the string properly using scm_from_stringn. If
+ CODESET is not supported, we won't be able to make much sense of
+ the returned string.
+
+ Note: We don't use Gnulib's `nl_langinfo' module because it's currently not
+ as complete as the compatibility hacks in `i18n.scm'. */
