+       In addition to the curses library, a system may provide its own
+       versions of the add-on libraries (form, menu, panel), which would
+       not be compatible with ncurses.  These options allow you to rename
+       ncurses' add-on libraries to avoid conflicts when linking:
+
+               --with-form-libname=XXX
+               --with-menu-libname=XXX
+               --with-panel-libname=XXX
+
+       Rather than renaming them abitrarily, a prefix or suffix is
+       recommended.  An "n" prefix provides consistency with ncurses versus
