gentoo-overlay/dev-libs/rocm-opencl-runtime/files/rocm-opencl-runtime-4.2.0-opencl3-header.patch

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.
