In w32term.c:w32_initialize, the line

  DWORD input_locale_id = (DWORD) GetKeyboardLayout (0);

(line 6666 in the current trunk) generates a "cast from pointer to 
integer of different size" warning in the cygw32 build on 64-bit Cygwin. 
 I think that the warning can be safely ignored in this case, but I 
would prefer to avoid it.

The attached patch fixes this.  I'm wondering, however, whether the same 
warning occurs on 64-bit Windows.  If so, maybe that should be fixed at 
the same time, but I don't know enough about Windows programming to do this.
