[xserver] DRIContextFlags...

[Etienne Robillard]

hi, 

i'm looking to compile xorg-server-1.13.99.901 from a tarball 
to improve general performance with intel i915 but having
issue locating the DRIContextFlags struct. 

Is this definition included into the xserver source tree or is provided
by another *proto package? If so, can you kindly point me to the
version and package needed to compile the xserver on linux or is
updating to the git development branch will resolve this issue ?

Kind regards,

Etienne
