2848 dnl shared library since that can lead to unexpected results at runtime.
2849 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
2850 dnl libraries are compiled in ../../lib
2851 dnl
2852 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
2853 dnl to install symbolic links to the rel/abi versions of shared libraries.
2854 dnl
2855 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
2856 dnl version when making symbolic links.
2857 dnl
2858 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
2859 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
2860 dnl (ex: libncurses.so.<ver>).
2861 dnl
2862 dnl Some loaders leave 'so_locations' lying around.  It's nice to clean up.
