308dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR], [ENABLED]).
309dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
310dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
311dnl    depending on --{enable,disable}-{shared,static} and on the presence of
312dnl    AM-DISABLE-SHARED). Otherwise, a static library
313dnl    $(top_builddir)/intl/libintl.a will be created.
314dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
315dnl    implementations (in libc or libintl) without the ngettext() function
316dnl    will be ignored.
317dnl LIBDIR is used to find the intl libraries.  If empty,
318dnl    the value `$(top_builddir)/intl/' is used.
319dnl ENABLED is used to control the default for the related --enable-nls, since
320dnl    not all application developers want this feature by default, e.g., lynx.
321dnl
322dnl The result of the configuration is one of three cases:
323dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
324dnl    and used.
325dnl    Catalog format: GNU --> install in $(datadir)
326dnl    Catalog extension: .mo after installation, .gmo in source tree
327dnl 2) GNU gettext has been found in the system's C library.
328dnl    Catalog format: GNU --> install in $(datadir)
329dnl    Catalog extension: .mo after installation, .gmo in source tree
330dnl 3) No internationalization, always use English msgid.
331dnl    Catalog format: none
332dnl    Catalog extension: none
333dnl The use of .gmo is historical (it was needed to avoid overwriting the
334dnl GNU format catalogs when building on a platform with an X/Open gettext),
335dnl but we keep it in order not to force irrelevant filename changes on the
336dnl maintainers.

3510dnl
3511dnl Notes:
3512dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
3513dnl the build-tree, i.e., by making use of the libraries that are compiled in
3514dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the

3516dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
3517dnl libraries are compiled in ../../lib
3518dnl
3519dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
3520dnl to install symbolic links to the rel/abi versions of shared libraries.
3521dnl
3522dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
3523dnl version when making symbolic links.
3524dnl
3525dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
3526dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
3527dnl (ex: libncurses.so.<ver>).

4043dnl -------------
4044dnl Check to see if the BSD-style union wait is declared.  Some platforms may
4045dnl use this, though it is deprecated in favor of the 'int' type in Posix.
4046dnl Some vendors provide a bogus implementation that declares union wait, but

4048dnl associated macros.
4049dnl
4050dnl Ahem.  Some implementers cast the status value to an int*, as an attempt to
4051dnl use the macros for either union wait or int.  So we do a check compile to

4135dnl (automake is a textbook-example of why the latter is a bad idea, but there
4136dnl are others).
4137dnl
4138dnl The file contents are:
4139dnl	libtool-version	release-version	patch-version
4140dnl or
4141dnl	release-version
4142dnl where
4143dnl	libtool-version (see ?) consists of 3 integers separated by '.'
4144dnl	release-version consists of a major version and minor version
4145dnl		separated by '.', optionally followed by a patch-version
4146dnl		separated by '-'.  The minor version need not be an
4147dnl		integer (but it is preferred).
4148dnl	patch-version is an integer in the form yyyymmdd, so ifdef's and
4149dnl		scripts can easily compare versions.
