2774 dnl the build-tree, i.e., by making use of the libraries that are compiled in

2777 dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
2778 dnl libraries are compiled in ../../lib
2780 dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
2781 dnl to install symbolic links to the rel/abi versions of shared libraries.
2783 dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
2784 dnl version when making symbolic links.
2786 dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
2787 dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
2788 dnl (ex: libncurses.so.<ver>).
