--- Comment #7 from Damjan Jovanovic  ---
Even with that change though, the drop target does not accept the drop, and the
drop is then sent over WM_DROPFILES instead, where it succeeds:

---snip---
0024:trace:xdnd:x11drv_dnd_drop_event the application refused the drop
0024:trace:xdnd:X11DRV_XDND_SendDropFiles Sending WM_DROPFILES:
hWnd=0x0001008A, fNC=0, x=735, y=559,
files=02F26934(L"Z:\store0\Projects\Wine\Research\55179-garmin-mapsource-cannot-dnd\Route_Paris_to_Madrid.gpx")
0024:trace:xdnd:x11drv_dnd_drop_event effectRequested(0x1) accept(1)
performed(0x1) at x(739),y(608)
---snip---

so I am not sure my change is correct.
