Patch contributed by Jason Tiller <jtiller@sjm.com> :
        * auto_load.cc: Add "GetKeyboardLayout" entry in the list of
        Win32 User32.DLL exports to provide.
        * fhandler.h (class fhandler_console): Add meta_mask private
        member to remember which keystroke modifiers should generate
        META.
        * fhandler_console.cc (fhandler_console::read): Modify code that
        tests a keystroke for a META-escaped key to use the 'meta_mask'
        variable.
        (fhandler_console::fhandler_console): Add definition for
        variable "meta_mask" used to determine if a keystroke should be
        preceded by META in the client console stream.  Set meta_mask
        based on whether or not user's keyboard language is English -
        non-English keyboards pass AltGr (right <ALT>) unmolested,
        whereas English keyboards now interpret left- and right-<ALT>
        as META.
