  //! \brief OpenCL run-time loader header
  //!
  //! This file contains a copy of the contents of CL.H and CL_PLATFORM.H from the 
  //! official OpenCL spec. The purpose of this code is to load the OpenCL dynamic
  //! library at run-time and thus allow the executable to function on many
  //! platforms regardless of the vendor of the OpenCL driver actually installed.
  //! Some of the techniques used here were inspired by work done in the GLEW
  //! library (http://glew.sourceforge.net/)
  
  //  Run-time dynamic linking functionality based on concepts used in GLEW

   * Vector types 
   *
   *  Note:   OpenCL requires that all types be naturally aligned. 
   *          This means that vector types must be naturally aligned.
   *          For example, a vector of four floats must be aligned to
   *          a 16 byte boundary (calculated as 4 * the natural 4-byte 
   *          alignment of the float).  The alignment qualifiers here
   *          will only function properly if your compiler supports them
   *          and if you don't actively work to defeat them.  For example,
   *          in order for a cl_float4 to be 16 byte aligned in a struct,
   *          the start of the struct must itself be 16-byte aligned. 
   *
   *          Maintaining proper alignment is the user's responsibility.

   * Usage:
   *   Place CL_PROGRAM_STRING_DEBUG_INFO on the line before the first line of your source. 
   *   The first line ends with:   CL_PROGRAM_STRING_BEGIN \"
   *   Each line thereafter of OpenCL C source must end with: \n\
   *   The last line ends in ";
   *
   *   Example:
   *
   *   const char *my_program = CL_PROGRAM_STRING_BEGIN "\
   *   kernel void foo( int a, float * b )             \n\
   *   {                                               \n\
