Perhaps I didn't explain properly:

I built wayland-egl from code in Mesa-17.0.4. That built
libwayland-egl.so.1.0.0. I rebuilt wayland-egl from your code in Mesa-17.1.9.
That also built libwayland-egl.so.1.0.0.

Between the 2 revisions, the layout of struct wl_egl_window is changed to have
const intptr_t version inserted as its first element with struct wl_surface
*surface moved from first element to last.

The new .so builds to be the same size as the old one but cmp -l shows 1395
differing bytes,

Cheers ... Duncan.
