Quoting for -I include paths

Hi there,

the CL standard allows passing “-I /some/where” to specify include directories for kernels, but it (AFAICT) does not specify how one would pass an include path containing spaces. Double quotes ("") work on a number of implementations, but, reportedly, not with Nvidia OpenCL. It would be great if the standard could just put this annoying issue to rest.

Thanks,
Andreas
