 This is akin to task #657 (add --with-openmp support to ./configure),
 which I still am very keen to see happen as we already have OpenMP-aware
 code in trunk. See that report for a basic summary & philosophy of
 approach.


 For now the OepnCL support would mainly be used for Seth's 2010 GSoC
 project to make r.sun use OpenCL, making it some hundreds of times faster,
 which we'd like to merge into trunk in the near future.

 note that even if you don't have a fancy GPU the OpenCL spec allows you to
 run the code on a multi-core CPU instead, so it's still nice. (maybe even
 both multi-core CPU '''and''' GPU ??)


 any help with the autoconf magic would be greatly appreciated.


 thanks,
 Hamish
