building X from source: xf86_video_intel build issues

[mike young]

Thanks again to Alan for helping with the previous issue - mesa/mesa now 
builds successfully.

The next build issue is encountered in the intel video driver 
xf86_video_intel:

...

sna_accel.c: In function âsna_accel_post_damageâ:
sna_accel.c:17699:14: error: âstruct _PixmapDirtyUpdateâ has no member 
named âslave_dstâ
    dst = dirty->slave_dst->master_pixmap;
               ^~
sna_accel.c:17726:28: error: âstruct _PixmapDirtyUpdateâ has no member 
named âslave_dstâ
    DamageRegionAppend(&dirty->slave_dst->drawable, &region);
                             ^~
sna_accel.c:17803:36: error: âstruct _PixmapDirtyUpdateâ has no member 
named âslave_dstâ
DamageRegionProcessPending(&dirty->slave_dst->drawable);
                                     ^~
make[4]: *** [Makefile:691: sna_accel.lo] Error 1
make[4]: Leaving directory '/home/m/src/driver/xf86-video-intel/src/sna'

Any thoughts? Thanks as always...
