Hello,

Using 4.99.58/i386 and trying to compile x11/xf86-video-i810 (from -HEAD),
I get the following error:
In file included from i810.h:46,
                 from i810_accel.c:55:

Any idea where this comes from ?
I'm using modular-xorg-server and a DRI kernel.

x11/xf86-video-intel compiles (and works) OK.

any thoughts ?
