+config OPTION_EGLIBC_LOCALE_CODE
+	bool "Locale functions"
+	depends on OPTION_POSIX_C_LANG_WIDE_CHAR
+	help
+		This option group includes locale support functions, programs,
+		and libraries.  With OPTION_EGLIBC_LOCALE_FUNCTIONS disabled,
+		EGLIBC supports only the 'C' locale (also known as 'POSIX'),
+		and ignores the settings of the 'LANG' and 'LC_*' environment
+		variables.
+
+		With OPTION_EGLIBC_LOCALE_CODE disabled, the following
+		functions are omitted from libc:
+
+		duplocale   localeconv  nl_langinfo    rpmatch  strfmon_l
+		freelocale  newlocale   nl_langinfo_l  strfmon  uselocale
+
+		Furthermore, only the LC_CTYPE and LC_TIME categories of the
+		standard "C" locale are available.

+		The OPTION_EGLIBC_CATGETS option group depends on this option
+		group; if you disable OPTION_EGLIBC_LOCALE_CODE, you must also
+		disable OPTION_EGLIBC_CATGETS.
+
+config OPTION_EGLIBC_CATGETS
+	bool "Functions for accessing message catalogs"
+	depends on OPTION_EGLIBC_LOCALE_CODE
+	help
+		This option group includes functions for accessing message
+		catalogs: catopen, catclose, and catgets.
+
+		This option group depends on the OPTION_EGLIBC_LOCALE_CODE
+		option group; if you disable that, you must also disable this.
+
+config OPTION_POSIX_WIDE_CHAR_DEVICE_IO
+	bool "Input and output functions for wide characters"
+	depends on OPTION_POSIX_C_LANG_WIDE_CHAR
+	help
+		This option group includes functions for reading and writing
+		wide characters to and from <stdio.h> streams.
+
+		This option group includes the following functions:
+
+		fgetwc        fwprintf      putwchar      vwscanf
+		fgetws        fwscanf       ungetwc       wprintf
+		fputwc        getwc         vfwprintf     wscanf
+		fputws        getwchar      vfwscanf
+		fwide         putwc         vwprintf
+
+		This option group further includes the following unlocked
+		variants of the above functions:
+
+		fgetwc_unlocked           getwc_unlocked
+		fgetws_unlocked           getwchar_unlocked
+		fputwc_unlocked           putwc_unlocked
+		fputws_unlocked           putwchar_unlocked
+
+		Note that the GNU standard C++ library, 'libstdc++.so', uses
+		some of these functions; you will not be able to link or run
+		C++ programs if you disable this option group.
+
+		This option group also affects the behavior of the following
+		functions:
+
+		fdopen
+		fopen
+		fopen64
+		freopen
+		freopen64
+
+		These functions all take an OPENTYPE parameter which may
+		contain a string of the form ",ccs=CHARSET", indicating that
+		the underlying file uses the character set named CHARSET.
+		This produces a wide-oriented stream, which is only useful
+		when the functions included in this option group are present.
+		If the user attempts to open a file specifying a character set
+		in the OPENTYPE parameter, and EGLIBC was built with this
+		option group disabled, the function returns NULL, and sets
+		errno to EINVAL.
