Thomas E. Dickey f70db18a0c ncurses 5.6 - patch 20061230
+ 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.
