        Handle properly the case when the index type is an enumerated type.
        Do not return the subtype of the bounds type, just return the
        bounds type directly - this is not needed and is more consistent

        appropriate.
        (win32_pid_to_exec_file): Use Cygwin's /proc interface to determine
        executable name.  Use get_module_name when that fails or when
