using (void*)0 could not pass compilation in clang 3.6. It will be treated as private address space pointer, if you compare a global pointer with NULL, that is a private and global pointer comparison, this is not allowed by OpenCL spec. But zero is allowed as it is a pointer and integer comparison.
