  18 /* Cygwin 1.5.x sets siginfo_t.si_addr to the instruction that faulted, not
  19    the address that the instruction tried to access.  This is fixed in
  20    Cygwin 1.7.  As a workaround, we use the fault address that was included
  21    in the EXCEPTION_POINTERS structure when Win32 signalled the exception.
  22    main_exception_filter stores this fault address before it passes control to
  23    Cygwin's exception filter which ultimately invokes the Unix signal
  24    handler.  */
