dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR], [ENABLED]).
dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/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). Otherwise, a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored.
dnl LIBDIR is used to find the intl libraries. If empty,
dnl the value `$(top_builddir)/intl/' is used.
dnl ENABLED is used to control the default for the related --enable-nls, since
dnl not all application developers want this feature by default, e.g., lynx.
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 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 CF_CONST_X_STRING version: 6 updated: 2021/01/01 13:31:04
dnl -----------------
dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
dnl character-strings.
dnl
dnl It is ambiguous because the specification accommodated the pre-ANSI
dnl compilers bundled by more than one vendor in lieu of providing a standard C
dnl compiler other than by costly add-ons. Because of this, the specification
dnl did not take into account the use of const for telling the compiler that
dnl string literals would be in readonly memory.
dnl
dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
dnl let the compiler decide how to represent Xt's strings which were #define'd.
dnl That does not solve the problem of using the block of Xt's strings which
dnl are compiled into the library (and is less efficient than one might want).
dnl
dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
dnl when compiling the library and compiling using the library, to tell the
dnl compiler that String is const.

dnl -------------------
dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting
dnl the CPPFLAGS variable so we can include its header.
dnl
dnl The header files may be installed as either curses.h, or ncurses.h (would
dnl be obsolete, except that some packagers prefer this name to distinguish it
dnl from a "native" curses implementation). If not installed for overwrite,
dnl the curses.h file would be in an ncurses subdirectory (e.g.,
dnl /usr/include/ncurses), but someone may have installed overwriting the
dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
dnl the header.
dnl
dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
dnl is already in the include-path, don't even bother with this, since we cannot
dnl easily determine which file it is. In this case, it has to be <curses.h>.
dnl
dnl The optional parameter gives the root name of the library, in case it is
dnl not installed as the default curses library. That is how the
dnl wide-character version of ncurses is installed.

dnl recent features visible in the system header files unless the application
dnl overrides the corresponding test-macros. Doing that introduces portability

dnl --------------
dnl --------------
dnl Attempt to determine the appropriate CC/LD options for creating a shared
dnl library.
dnl
dnl Notes:
dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
dnl the build-tree, i.e., by making use of the libraries that are compiled in
dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
dnl shared library since that can lead to unexpected results at runtime.
dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
dnl libraries are compiled in ../../lib
dnl
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
dnl to install symbolic links to the rel/abi versions of shared libraries.
dnl
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
dnl version when making symbolic links.
dnl
dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
dnl (ex: libncurses.so.<ver>).
dnl
dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.

dnl CF_VERSION_INFO version: 8 updated: 2021/01/01 13:31:04
dnl ---------------
dnl Define several useful symbols derived from the VERSION file. A separate
dnl file is preferred to embedding the version numbers in various scripts.
dnl (automake is a textbook-example of why the latter is a bad idea, but there
dnl are others).
dnl
dnl The file contents are:
dnl libtool-version release-version patch-version
dnl or
dnl release-version
dnl where
dnl libtool-version (see ?) consists of 3 integers separated by '.'
dnl release-version consists of a major version and minor version
dnl separated by '.', optionally followed by a patch-version
dnl separated by '-'. The minor version need not be an
dnl integer (but it is preferred).
dnl patch-version is an integer in the form yyyymmdd, so ifdef's and
dnl scripts can easily compare versions.
dnl
dnl If libtool is used, the first form is required, since CF_WITH_LIBTOOL
dnl simply extracts the first field using 'cut -f1'.
dnl
dnl Optional parameters:
dnl $1 = internal name for package
dnl $2 = external name for package
