Giving compile options to clBuildProgram

[joergdw]

Sometimes you have to generate macros automatically by the host program and inject them in the OpenCL-C code before it is compiled. In the C++-API therefore you can give the clBuildProgram-call a pointer to an option string. In the current version of the Haskell-API you can simulate this behaviour by prepending this string to the one you give the Haskell-call to compile. Unfortunately if you do this, the line number increases and if you receive an error message by the cl-compiler the line numbers it tells are too high.

Therefore it would be nice to be able to give the Haskell-call an additional (possibly empty) String and change it's signature to:
clBuildProgram :: CLProgram -> [CLDeviceID] -> String -> String -> IO ()
