	help
	  This option group specifies whether certain pieces of code
	  should be inlined to achieve maximum speed.  If this option
	  group is not selected, function calls will be used instead,
	  hence reducing the library footprint.


config EGLIBC_OPTION_EGLIBC_BSD
	bool "BSD-specific functions, and their compatibility stubs"
	default y
	help
	  This option group includes functions specific to BSD kernels.
	  A number of these functions have stub versions that are also

	  This option group does not include any C library functions;
	  instead, it controls which EGLIBC tests an ordinary 'make
	  tests' runs.  With this group disabled, tests that would
	  normally link against the standard C++ library are not
	  run.

	  The standard C++ library depends on the math library 'libm' and
	  the wide character I/O functions included in EGLIBC.  If those

	  - The rpcgen, nscd, and rpcinfo commands are not installed.

	  - The 'rpc' file (a text file listing RPC services) is not installed.

	  Socket-related system calls do not fall in this option group,
	  because many are also used for other inter-process
	  communication mechanisms.  For example, the 'syslog' routines
	  use Unix-domain sockets to communicate with the syslog daemon;
	  syslog is valuable in non-networked contexts.


config EGLIBC_OPTION_EGLIBC_LIBM
	bool "libm (math library)"
	default y
	help
	  This option group includes the 'libm' library, containing
	  mathematical functions.  If this option group is omitted, then
	  an EGLIBC installation does not include shared or unshared versions
	  of the math library.

	  Note that this does not remove all floating-point related
	  functionality from EGLIBC; for example, 'printf' and 'scanf'
	  can still print and read floating-point values with this option
	  group disabled.

	  Note that the ISO Standard C++ library 'libstdc++' depends on
	  EGLIBC's math library 'libm'.  If you disable this option
	  group, you will not be able to build 'libstdc++' against the
	  resulting EGLIBC installation.


config EGLIBC_OPTION_EGLIBC_LOCALES
	bool "Locale definitions"
	default y
	help
	  This option group includes all locale definitions other than
	  that for the "C" locale.  If this option group is omitted, then
	  only the "C" locale is supported.

	default y
	select EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR if EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10 || EGLIBC_VERSION_2_11
	help
	  This option group includes locale support functions, programs,
	  and libraries.  With EGLIBC_OPTION_EGLIBC_LOCALE_CODE disabled,
	  EGLIBC supports only the 'C' locale (also known as 'POSIX'),
	  and ignores the settings of the 'LANG' and 'LC_*' environment
	  variables.

	  With EGLIBC_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 EGLIBC_OPTION_EGLIBC_CATGETS option group depends on this option
	  group; if you disable EGLIBC_OPTION_EGLIBC_LOCALE_CODE, you must also
	  disable EGLIBC_OPTION_EGLIBC_CATGETS.


config EGLIBC_OPTION_EGLIBC_MEMUSAGE
	bool "Memory profiling library"
	default y
	depends EGLIBC_VERSION_2_11
	help
	  This option group includes the `libmemusage' library and
	  the `memusage' and `memusagestat' utilities.
	  These components provide memory profiling functions.

	  EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE

	  Libmemusage library buffers the profiling data in memory
	  before writing it out to disk.  By default, the library
	  allocates 1.5M buffer, which can be substantial for some
	  systems.  EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE option
	  allows to change the default buffer size.  It specifies
	  the number of entries the buffer should have.
	  On most architectures one buffer entry amounts to 48 bytes,
	  so setting this option to the value of 512 will reduce the size of
	  the memory buffer to 24K.

	  This option group includes the NIS, NIS+, and 'compat' Name
	  Service Switch service libraries.  When it is disabled, those
	  services libraries are not installed; you should remove any
	  references to them from your 'nsswitch.conf' file.

	  This option group depends on the EGLIBC_OPTION_EGLIBC_INET option
	  group; you must enable that to enable this option group.


config EGLIBC_OPTION_EGLIBC_NSSWITCH

	  This option group includes support for the 'nsswitch' facility.
	  With this option group enabled, all EGLIBC functions for
	  accessing various system databases (passwords and groups;
	  networking; aliases; public keys; and so on) consult the
	  '/etc/nsswitch.conf' configuration file to decide how to handle
	  queries.

	  With this option group disabled, EGLIBC uses a fixed list of
	  services to satisfy queries on each database, as requested by
	  configuration files specified when EGLIBC is built.  Your
	  'option-groups.config' file must set the following two
	  variables:

	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG

		Set this to the name of a file whose contents observe the
		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
		EGLIBC build process parses this file just as EGLIBC would
		at run time if EGLIBC_NSSWITCH were enabled, and
		produces a C library that uses the nsswitch service
		libraries to search for database entries as this file
		specifies, instead of consulting '/etc/nsswitch.conf' at run
		time.

		This should be an absolute filename.  The EGLIBC build
		process may use it from several different working
		directories.  It may include references to Makefile
		variables like 'common-objpfx' (the top of the build tree,
		with a trailing slash), or '..' (the top of the source tree,
		with a trailing slash).

		The EGLIBC source tree includes a sample configuration file
		named 'nss/fixed-nsswitch.conf'; for simple configurations,
		you will probably want to delete references to databases not
		needed on your system.

	  EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS

		The EGLIBC build process uses this file to decide which
		functions to make available from which service libraries.
		The file 'nss/fixed-nsswitch.functions' serves as a sample
		configuration file for this setting, and explains its syntax
		and meaning in more detail.

		This should be an absolute file name.  The EGLIBC build
		process may use it from several different working
		directories.  It may include references to Makefile
		variables like 'common-objpfx' (the top of the build tree,
		with a trailing slash), or '..' (the top of the source tree,
		with a trailing slash).

		Be sure to mention each function in each service you wish to
		use.  If you do not mention a service's function here, the
		EGLIBC database access functions will not find it, even if
		it is listed in the EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
		file.

	  In this arrangement, EGLIBC will not use the 'dlopen' and
	  'dlsym' functions to find database access functions.  Instead,
	  libc hard-codes references to the service libraries' database
	  access functions.  You must explicitly link your program
	  against the name service libraries (those whose names start
	  with 'libnss_', in the sysroot's '/lib' directory) whose
	  functions you intend to use.  This arrangement helps
	  system-wide static analysis tools decide which functions a
	  system actually uses.

	  Note that some nsswitch service libraries require other option
	  groups to be enabled; for example, the EGLIBC_OPTION_EGLIBC_INET
	  option group must be enabled to use the 'libnss_dns.so.2'
	  service library, which uses the Domain Name System network
	  protocol to answer queries.


config EGLIBC_OPTION_EGLIBC_RCMD
	bool "Support for 'rcmd' and related library functions"
	default y
	select EGLIBC_OPTION_EGLIBC_INET
	help
	  This option group includes functions for running commands on
	  remote machines via the 'rsh' protocol, and doing authentication

		posix_spawnp

	  This option group also provides the ability for the iconv,
	  localedef, and locale programs to operate transparently on
	  compressed charset definitions.  When this option group is
	  disabled, those programs will only operate on uncompressed
	  charmap files.


config EGLIBC_OPTION_EGLIBC_STREAMS
	bool "Support for accessing STREAMS."
	default y
	help
	  This option group includes functions for reading and writing
	  messages to and from STREAMS.  The STREAMS interface provides a
	  uniform mechanism for implementing networking services and other
	  character-based I/O.  (STREAMS are not to be confused with
	  <stdio.h> FILE objects, also called 'streams'.)

	  This option group includes the following functions:

	  including the 'rpcgen' and 'rpcinfo' programs.


config EGLIBC_OPTION_EGLIBC_UTMP
	bool "Older access functions for 'utmp' login records"
	default y
	help
	  This option group includes the older 'utent' family of
	  functions for accessing user login records in the 'utmp' file.
	  POSIX omits these functions in favor of the 'utxent' family,
	  and they are obsolete on systems other than Linux.

	  This option group includes the following functions:

		endutent
		getutent
		getutent_r
		getutid
		getutid_r
		getutline
		getutline_r
		logwtmp
		pututline
		setutent
		updwtmp
		utmpname

	  This option group includes the following libraries:

		libutil.so (and libutil.a)


config EGLIBC_OPTION_EGLIBC_UTMPX
	bool "POSIX access functions for 'utmp' login records"
	default y
	select EGLIBC_OPTION_EGLIBC_UTMP    
	help
	  This option group includes the POSIX functions for reading and
	  writing user login records in the 'utmp' file (usually
	  '/var/run/utmp').  The POSIX functions operate on 'struct
	  utmpx' structures, as opposed to the family of older 'utent'
	  functions, which operate on 'struct utmp' structures.

	  This option group includes the following functions:

		endutxent
		getutmp
		getutmpx
		getutxent
		getutxid
		getutxline

	default y
	depends EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10 || EGLIBC_VERSION_2_11
	help
	  This option group includes the functions defined by the ISO C
	  standard for working with wide and multibyte characters in
	  memory.  Functions for reading and writing wide and multibyte
	  characters from and to files call in the
	  EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO option group.

	  This option group includes the following functions:

config EGLIBC_OPTION_POSIX_REGEXP
	bool "Regular expressions"
	default y
	help
	  This option group includes the POSIX regular expression
	  functions, and the associated non-POSIX extensions and
	  compatibility functions.

	  With EGLIBC_OPTION_POSIX_REGEXP disabled, the following functions are
	  omitted from libc:

		re_comp                 re_max_failures         regcomp
		re_compile_fastmap      re_search               regerror

		re_match                re_set_syntax           rpmatch
		re_match_2              re_syntax_options

	  Furthermore, the compatibility regexp interface defined in the
	  <regexp.h> header file, 'compile', 'step', and 'advance', is
	  omitted.


config EGLIBC_OPTION_POSIX_REGEXP_GLIBC
	bool "Regular expressions from GLIBC"
	default y
	depends EGLIBC_VERSION_2_10 || EGLIBC_VERSION_2_11
	select EGLIBC_OPTION_POSIX_REGEXP
	help
	  This option group specifies which regular expression
	  library to use.  The choice is between regex
	  implementation from GLIBC and regex implementation from
	  libiberty.  The GLIBC variant is fully POSIX conformant and
	  optimized for speed; regex from libiberty is more than twice
	  as small while still is enough for most practical purposes.


config EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
	bool "Input and output functions for wide characters"
	default y
	select EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR if EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10 || EGLIBC_VERSION_2_11
	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.
