I've been trying to a copy of the Mesa tree that has the Rotation and 945GM
support that Alan H. checked in and it looks to me like the CVS tip does not
currently build. I get:
make[3]: Entering directory `/root/mesa/Mesa/src/glx/x11'
gcc -c -I. -I../../../include
I'm down to trying to build the i915_dri driver and am getting:
gcc -c -I. -I../../../../../src/mesa/drivers/dri/common -Iserver
-I../../../../../../drm/shared-core -I../../../../../include
-I../../../../../include/GL/internal -I../../../../../src/mesa
-I../../../../../src/mesa/main
