Unreviewed crash fix for Windows port.

Becuase Windows port doesn't use IPC::Attachment, IPC::Attachment was
defined as an alias to int on Windows. After 273876 at main added a
encoder and decoder for IPC::Attachment, all int value were encoded as
IPC::Attachment.

IPC::Attachment should be a unique type.
