Comment(by hamish):

 OpenCL infrastructure support added to configure[.in],
 include/Make/Platform.make, and raster/r.sun/Makefile,main.c in r55949,50.

 It could do with a little more work,
  - my libOpenCL.so is in /opt and listed in '`ldconfig -p`', but
 autoconf's gcc conftest doesn't find -lOpenCL. Symlinking into
 /usr/local/lib works, but why is that needed?
  - OCLLIBPATH is not being set from --with-opencl-libs= (see trac #1943)
  - to use LOC_CHECK_FUNC(,LOC_CHECK_LIBS()) or just LOC_CHECK_LIBS()?
  - remove unused variables from r.sun's Makefile


 have fun,
 Hamish
