Thomas E. Dickey c6540b9c89 ncurses 5.7 - patch 20100123
+ for term-driver configuration, ensure that the driver pointer is
  initialized in setupterm so that terminfo/termcap programs work.
+ amend fix for Debian #542031 to ensure that wattrset() returns only
  OK or ERR, rather than the attribute value (report by Miroslav
  Lichvar).
+ reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making
  _nc_screen_of() compatible between normal/wide libraries again (patch
  by Miroslav Lichvar)
+ review/fix include-dependencies in modules files (report by Miroslav
  Lichvar).
