ncursesw-morphos/ncurses/curses.priv.h
Thomas E. Dickey c002077d39 ncurses 5.9 - patch 20110813 
+ add substitution for $RPATH_LIST to misc/ncurses-config.in
+ improve performance of tic with hashed-database by caching the
  database connection, using atexit() to cleanup.
+ modify treatment of 2-character aliases at the beginning of termcap
  entries so they are not counted in use-resolution, since these are
  guaranteed to be unique.  Also ignore these aliases when reporting
  the primary name of the entry (cf: 20040501)
+ double-check gn (generic) flag in terminal descriptions to
  accommodate old/buggy termcap databases which misused that feature.
+ minor fixes to _nc_tgetent(), ensure buffer is initialized even on
  error-return.
