dnl Note: $(LOCAL_LDFLAGS) is used to link executables that will run within the

dnl We avoid compiling-in a ../lib path for the shared library since that can
dnl lead to unexpected results at runtime.

dnl 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 ---------------
dnl Provide a configure option to incorporate libtool.  Define several useful

dnl
dnl The reference to AC_PROG_LIBTOOL does not normally work, since it uses
dnl macros from libtool.m4 which is in the aclocal directory of automake.
dnl Following is a simple script which turns on the AC_PROG_LIBTOOL macro.
dnl But that still does not work properly since the macro is expanded outside
dnl the CF_WITH_LIBTOOL macro:
dnl
dnl	#!/bin/sh
dnl	ACLOCAL=`aclocal --print-ac-dir`
dnl	if test -z "$ACLOCAL" ; then
dnl		echo cannot find aclocal directory
dnl		exit 1
dnl	elif test ! -f $ACLOCAL/libtool.m4 ; then
dnl		echo cannot find libtool.m4 file
dnl		exit 1
dnl	fi
dnl	
dnl	LOCAL=aclocal.m4
dnl	ORIG=aclocal.m4.orig
dnl	
dnl	trap "mv $ORIG $LOCAL" 0 1 2 5 15
dnl	rm -f $ORIG
dnl	mv $LOCAL $ORIG
dnl	
dnl	# sed the LIBTOOL= assignment to omit the current directory?
