dnl @synopsis AC_caolan_FUNC_WHICH_GETHOSTBYNAME_R
dnl
dnl Provides a test to determine the correct
dnl way to call gethostbyname_r:
dnl
dnl  - defines HAVE_FUNC_GETHOSTBYNAME_R_6 if it needs 6 arguments (e.g linux)
dnl  - defines HAVE_FUNC_GETHOSTBYNAME_R_5 if it needs 5 arguments (e.g. solaris)
dnl  - defines HAVE_FUNC_GETHOSTBYNAME_R_3 if it needs 3 arguments (e.g. osf/1)
dnl
dnl If used in conjunction in gethostname.c the api demonstrated
dnl in test.c can be used regardless of which gethostbyname_r
dnl exists. These example files found at
dnl <http://www.csn.ul.ie/~caolan/publink/gethostbyname_r>.
dnl
dnl Based on David Arnold's autoconf suggestion in the threads faq.

# Macro to add for using GNU gettext.

#
# This file can be copied and used freely without restrictions.  It can
# be used in projects which are not available under the GNU General Public

# serial 10

dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
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
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.
