commit 229064524b0384ac3e7397ebe29424b8d6ddb11c
Author: Jeroen Ketema <j.ketema at imperial.ac.uk>
Date:   Tue Nov 18 14:19:27 2014 +0000

    Don't include <stddef.h>
    
    Including a standard or system header isn't allowed in OpenCL.
    
    The type "size_t" needs to be explicitely defined now.
    
    v2: Use __SIZE_TYPE__ instead of unsigned int.
    v3: Define ptrdiff_t and NULL.
