+See bug #789717.
+
+Once opencl-headers is upgraded to 3.0 or higher this package starts
+complaining left and right about missing header definitions for
+CL_COMMAND_GL_FENCE_SYNC_OBJECT_KHR.  The correct header for this
+definiton did move as of opencl-headers 3.0 so this makes some sense.
+(Actually I suspect there is a header-guard mismatch behind this problem).
+
+Most of this can be fixed by using -isystem instead of -I for the opencl
+headers. Although not terribly well documented, -isystem in lieu of -I
+comports with best practices for overriding 3rd-party header files in
+system include directories according to the gcc info pages.  Why and how
+are apparently undocumented and appear to be somewhere inside the gcc
+fixincludes rabbit-hole.
+
+This still leaves a similar issue compiling the amdocl files which
+is addressed here with an extra #include.
