-dnl They are *not* in the public domain.

-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    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(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 Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
-dnl
-dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
-dnl 'include' otherwise.
-dnl
-dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
-dnl supports it in the special case that it is the first include directive in
-dnl the given file, or to 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.

-dnl ------------
-dnl Tests for a multithreading library to be used.
-dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
-dnl USE_PTH_THREADS, USE_WIN32_THREADS
-dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
-dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
-dnl libtool).
-dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
-dnl programs that really need multithread functionality. The difference
-dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
-dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
-dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
-dnl multithread-safe programs.
