[PATCH 6/8] [PATCH for ZBar] Make zbargtk build on Windows

[Руслан Ижбулатов <lrn1986@xxxxxxxxx>]

The code is mostly platform-agnostic, except for this small part
that is written for X. Add ifdefs with an appropriate W32 header,
and call zbar_window_attach() with correct W32 arguments.
Use HAVE_X as a condition.
