+ modify configure check for libtool's version to trim blank lines (report by sci-fi@hush.ai). + modify some modules to allow them to be reentrant if _REENTRANT is defined: lib_baudrate.c, resizeterm.c (local data only) + eliminate static data from some modules: add_tries.c, hardscroll.c, lib_ttyflags.c, lib_twait.c + improve manpage install to add aliases for the transformed program names, e.g., from --program-prefix. + used linklint to verify links in the HTML documentation, made fixes to manpages as needed. + fix a typo in curs_mouse.3x (report by William McBrine). + fix install-rule for ncurses5-config to make the bin-directory.
