ncurses 6.4 - patch 20230211

+ set dwShareMode in calls to CreateConsoleScreenBuffer() (patch by
  Hannes Domani).
+ use CreateFile with "CONIN$", "CONOUT$" rather than GetStdHandle to
  obtain a handle on the actual console, avoiding redirection in the
  MinGW/Win32 configurations (adapted from patch by LIU Hao).
