-1 Notes on the Free Translation Project
-***************************************
-
-Free software is going international!  The Free Translation Project is
-a way to get maintainers of free software, translators, and users all
-together, so that free software will gradually become able to speak many
-languages.  A few packages already provide translations for their
-messages.
-
-   If you found this `ABOUT-NLS' file inside a distribution, you may
-assume that the distributed package does use GNU `gettext' internally,
-itself available at your nearest GNU archive site.  But you do _not_
-need to install GNU `gettext' prior to configuring, installing or using
-this package with messages translated.
-
-   Installers will find here some useful hints.  These notes also
-explain how users should proceed for getting the programs to use the
-available translations.  They tell how people wanting to contribute and
-work on translations can contact the appropriate team.
-
-   When reporting bugs in the `intl/' directory or bugs which may be
-related to internationalization, you should tell about the version of
-`gettext' which is used.  The information can be found in the
-`intl/VERSION' file, in internationalized packages.
-
-1.1 Quick configuration advice
-==============================
-
-If you want to exploit the full power of internationalization, you
-should configure it using
-
-     ./configure --with-included-gettext
-
-to force usage of internationalizing routines provided within this
-package, despite the existence of internationalizing capabilities in the
-operating system where this package is being installed.  So far, only
-the `gettext' implementation in the GNU C library version 2 provides as
-many features (such as locale alias, message inheritance, automatic
-charset conversion or plural form handling) as the implementation here.
-It is also not possible to offer this additional functionality on top
-of a `catgets' implementation.  Future versions of GNU `gettext' will
-very likely convey even more functionality.  So it might be a good idea
-to change to GNU `gettext' as soon as possible.
-
-   So you need _not_ provide this option if you are using GNU libc 2 or
-you have installed a recent copy of the GNU gettext package with the
-included `libintl'.
-
-1.2 INSTALL Matters
-===================
-
-Some packages are "localizable" when properly installed; the programs
-they contain can be made to speak your own native language.  Most such
-packages use GNU `gettext'.  Other packages have their own ways to
-internationalization, predating GNU `gettext'.
-
-   By default, this package will be installed to allow translation of
-messages.  It will automatically detect whether the system already
-provides the GNU `gettext' functions.  If not, the included GNU
-`gettext' library will be used.  This library is wholly contained
-within this package, usually in the `intl/' subdirectory, so prior
-installation of the GNU `gettext' package is _not_ required.
-Installers may use special options at configuration time for changing
-the default behaviour.  The commands:
-
-     ./configure --with-included-gettext
-     ./configure --disable-nls
-
-will, respectively, bypass any pre-existing `gettext' to use the
-internationalizing routines provided within this package, or else,
-_totally_ disable translation of messages.
-
-   When you already have GNU `gettext' installed on your system and run
-configure without an option for your new package, `configure' will
-probably detect the previously built and installed `libintl.a' file and
-will decide to use this.  This might not be desirable.  You should use
-the more recent version of the GNU `gettext' library.  I.e. if the file
-`intl/VERSION' shows that the library which comes with this package is
-more recent, you should use
-
-     ./configure --with-included-gettext
-
-to prevent auto-detection.
-
-   The configuration process will not test for the `catgets' function
-and therefore it will not be used.  The reason is that even an
-emulation of `gettext' on top of `catgets' could not provide all the
-extensions of the GNU `gettext' library.
-
-   Internationalized packages usually have many `po/LL.po' files, where
-LL gives an ISO 639 two-letter code identifying the language.  Unless
-translations have been forbidden at `configure' time by using the
-`--disable-nls' switch, all available translations are installed
-together with the package.  However, the environment variable `LINGUAS'
-may be set, prior to configuration, to limit the installed set.
-`LINGUAS' should then contain a space separated list of two-letter
-codes, stating which languages are allowed.
-
-1.3 Using This Package
-======================
-
-As a user, if your language has been installed for this package, you
-only have to set the `LANG' environment variable to the appropriate
-`LL_CC' combination.  If you happen to have the `LC_ALL' or some other
-`LC_xxx' environment variables set, you should unset them before
-setting `LANG', otherwise the setting of `LANG' will not have the
-desired effect.  Here `LL' is an ISO 639 two-letter language code, and
-`CC' is an ISO 3166 two-letter country code.  For example, let's
-suppose that you speak German and live in Germany.  At the shell
-prompt, merely execute `setenv LANG de_DE' (in `csh'),
-`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
-This can be done from your `.login' or `.profile' file, once and for
-all.
-
-   You might think that the country code specification is redundant.
-But in fact, some languages have dialects in different countries.  For
-example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
-country code serves to distinguish the dialects.
-
-   The locale naming convention of `LL_CC', with `LL' denoting the
-language and `CC' denoting the country, is the one use on systems based
-on GNU libc.  On other systems, some variations of this scheme are
-used, such as `LL' or `LL_CC.ENCODING'.  You can get the list of
-locales supported by your system for your language by running the
-command `locale -a | grep '^LL''.
-
-   Not all programs have translations for all languages.  By default, an
-English message is shown in place of a nonexistent translation.  If you
-understand other languages, you can set up a priority list of languages.
-This is done through a different environment variable, called
-`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
-for the purpose of message handling, but you still need to have `LANG'
-set to the primary language; this is required by other parts of the
-system libraries.  For example, some Swedish users who would rather
-read translations in German than English for when Swedish is not
-available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
-
-   Special advice for Norwegian users: The language code for Norwegian
-bokma*l changed from `no' to `nb' recently (in 2003).  During the
-transition period, while some message catalogs for this language are
-installed under `nb' and some older ones under `no', it's recommended
-for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
-older translations are used.
-
-   In the `LANGUAGE' environment variable, but not in the `LANG'
-environment variable, `LL_CC' combinations can be abbreviated as `LL'
-to denote the language's main dialect.  For example, `de' is equivalent
-to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
-(Portuguese as spoken in Portugal) in this context.
-
-1.4 Translating Teams
-=====================
-
-For the Free Translation Project to be a success, we need interested
-people who like their own language and write it well, and who are also
-able to synergize with other translators speaking the same language.
-Each translation team has its own mailing list.  The up-to-date list of
-teams can be found at the Free Translation Project's homepage,
-`http://translationproject.org/', in the "Teams" area.
-
-   If you'd like to volunteer to _work_ at translating messages, you
-should become a member of the translating team for your own language.
-The subscribing address is _not_ the same as the list itself, it has
-`-request' appended.  For example, speakers of Swedish can send a
-message to `sv-request@li.org', having this message body:
-
-     subscribe
-
-   Keep in mind that team members are expected to participate
-_actively_ in translations, or at solving translational difficulties,
-rather than merely lurking around.  If your team does not exist yet and
-you want to start one, or if you are unsure about what to do or how to
-get started, please write to `coordinator@translationproject.org' to
-reach the coordinator for all translator teams.
-
-   The English team is special.  It works at improving and uniformizing
-the terminology in use.  Proven linguistic skills are praised more than
-programming skills, here.
-
-1.5 Available Packages
-======================
-
-Languages are not equally supported in all packages.  The following
-matrix shows the current state of internationalization, as of November
-2007.  The matrix shows, in regard of each package, for which languages
-PO files have been submitted to translation coordination, with a
-translation percentage of at least 50%.

-visible blocks let us expect.  This is because a few extra PO files are
-used for implementing regional variants of languages, or language
-dialects.
-
-   For a PO file in the matrix above to be effective, the package to
-which it applies should also have been internationalized and
-distributed as such by its maintainer.  There might be an observable
-lag between the mere existence a PO file and its wide availability in a
-distribution.

-1.6 Using `gettext' in new packages
-===================================
-
-If you are writing a freely available program and want to
-internationalize it you are welcome to use GNU `gettext' in your
-package.  Of course you have to respect the GNU Library General Public
-License which covers the use of the GNU `gettext' library.  This means
-in particular that even non-free programs can use `libintl' as a shared
-library, whereas only free software can use `libintl' as a static
-library or use modified versions of `libintl'.
-
-   Once the sources are changed appropriately and the setup can handle
-the use of `gettext' the only thing missing are the translations.  The
-Free Translation Project is also available for packages which are not
-developed inside the GNU project.  Therefore the information given above
-applies also for every other Free Software Project.  Contact
-`coordinator@translationproject.org' to make the `.pot' files available
-to the translation teams.

+dnl Written by Bruno Haible.
+
+dnl When the build environment ($build_os) is different from the target runtime
+dnl environment ($host_os), file names may need to be converted from the build
+dnl environment syntax to the target runtime environment syntax. This is
+dnl because the Makefiles are executed (mostly) by build environment tools and
+dnl therefore expect file names in build environment syntax, whereas the runtime
+dnl expects file names in target runtime environment syntax.
+dnl
+dnl For example, if $build_os = cygwin and $host_os = mingw32, filenames need
+dnl be converted from Cygwin syntax to native Windows syntax:
+dnl   /cygdrive/c/foo/bar -> C:\foo\bar
+dnl   /usr/local/share    -> C:\cygwin64\usr\local\share
+dnl
+dnl gl_BUILD_TO_HOST([somedir])
+dnl This macro takes as input an AC_SUBSTed variable 'somedir', which must
+dnl already have its final value assigned, and produces two additional
+dnl AC_SUBSTed variables 'somedir_c' and 'somedir_c_make', that designate the
+dnl same file name value, just in different syntax:
+dnl   - somedir_c       is the file name in target runtime environment syntax,
+dnl                     as a C string (starting and ending with a double-quote,
+dnl                     and with escaped backslashes and double-quotes in
+dnl                     between).
+dnl   - somedir_c_make  is the same thing, escaped for use in a Makefile.

 dnl Macro to add for using GNU gettext.
 
 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl INTLSYMBOL must be one of 'external', 'use-libtool', 'here'.
+dnl    INTLSYMBOL should be 'external' for packages other than GNU gettext.
+dnl    It should be 'use-libtool' for the packages 'gettext-runtime' and
+dnl    'gettext-tools'.
+dnl    It should be 'here' for the package 'gettext-runtime/intl'.
+dnl    If INTLSYMBOL is 'here', then a libtool library
+dnl    $(top_builddir)/libintl.la will be created (shared and/or static,
 dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl    AM-DISABLE-SHARED).
 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
 dnl    implementations (in libc or libintl) without the ngettext() function
 dnl    will be ignored.  If NEEDSYMBOL is specified and is
 dnl    'need-formatstring-macros', then GNU gettext implementations that don't
 dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
 dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
+dnl    the value '$(top_builddir)/intl/' is used.

+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its

+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can

+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test __BIG_ENDIAN__ vs. __LITTLE_ENDIAN__.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will
+dnl     need to make the distinction.
+dnl   - Speed of execution of the common instruction set is reasonable across
+dnl     the entire family of CPUs. If you have assembly language source files

+dnl Written by Bruno Haible.
+
+dnl When the build environment ($build_os) is different from the target runtime
+dnl environment ($host_os), file names may need to be converted from the build
+dnl environment syntax to the target runtime environment syntax. This is
+dnl because the Makefiles are executed (mostly) by build environment tools and
+dnl therefore expect file names in build environment syntax, whereas the runtime
+dnl expects file names in target runtime environment syntax.
+dnl
+dnl For example, if $build_os = cygwin and $host_os = mingw32, filenames need
+dnl be converted from Cygwin syntax to native Windows syntax:
+dnl   /cygdrive/c/foo/bar -> C:\foo\bar
+dnl   /usr/local/share    -> C:\cygwin64\usr\local\share
+dnl
+dnl gl_BUILD_TO_HOST([somedir])
+dnl This macro takes as input an AC_SUBSTed variable 'somedir', which must
+dnl already have its final value assigned, and produces two additional
+dnl AC_SUBSTed variables 'somedir_c' and 'somedir_c_make', that designate the
+dnl same file name value, just in different syntax:
+dnl   - somedir_c       is the file name in target runtime environment syntax,
+dnl                     as a C string (starting and ending with a double-quote,
+dnl                     and with escaped backslashes and double-quotes in
+dnl                     between).
+dnl   - somedir_c_make  is the same thing, escaped for use in a Makefile.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL must be one of 'external', 'use-libtool', 'here'.
+dnl    INTLSYMBOL should be 'external' for packages other than GNU gettext.
+dnl    It should be 'use-libtool' for the packages 'gettext-runtime' and
+dnl    'gettext-tools'.
+dnl    It should be 'here' for the package 'gettext-runtime/intl'.
+dnl    If INTLSYMBOL is 'here', then a libtool library
+dnl    $(top_builddir)/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED).
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl   will not run on SPARC CPUs and vice versa. They have different
+dnl   instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl   mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl   different argument passing and return conventions for C functions, and
+dnl   although the instruction set of 'mips' is a large subset of the
+dnl   instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl   different sizes for the C types like 'int' and 'void *', and although
+dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl   determine the endianness through preprocessor symbols:
+dnl   - 'arm': test __ARMEL__.
+dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl   - 'powerpc64': test __BIG_ENDIAN__ vs. __LITTLE_ENDIAN__.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl     assembly language source files use such instructions, you will
+dnl     need to make the distinction.
+dnl   - Speed of execution of the common instruction set is reasonable across
+dnl     the entire family of CPUs. If you have assembly language source files
+dnl     that are optimized for particular CPU types (like GNU gmp has), you
+dnl     will need to make the distinction.
