dnl --------------
dnl --------------
dnl Attempt to determine the appropriate CC/LD options for creating a shared
dnl library.
dnl
dnl Note: ${LOCAL_LDFLAGS} is used to link executables that will run within the
dnl build-tree, i.e., by making use of the libraries that are compiled in ../lib
dnl We avoid compiling-in a ../lib path for the shared library since that can
dnl lead to unexpected results at runtime.
dnl ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared libraries
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.
