+SHLIB_LIBPREF  The prefix to use when generating the filename of the shared
+               library.  The default is `lib'; Cygwin uses `cyg'.

 SHLIB_LIBSUFF  The suffix to add to `libreadline' and `libhistory' when
                generating the filename of the shared library.  Many systems

+SHLIB_DLLVERSION The version number for shared libraries that determines API

 SHLIB_STATUS   Set this to `supported' when you have defined the other
                necessary variables.  Make uses this to determine whether
                or not shared library creation should be attempted.  If
