[OpenCL] Possible bug at CL.CreateProgramWithBinary

Description

I think these two signatures don't quite match. Note the
byte @char
and
const unsigned char **binaries
parameters. Shouldn't it be string[]?
C#:

public static IntPtr CreateProgramWithBinary( 
             IntPtr context, 
             int num_devices, 
             IntPtr* device_list, 
             IntPtr* lengths, 
             byte @char, 
             int* binary_status, 
             ErrorCode* errcode_ret );

OpenCL:

cl_program clCreateProgramWithBinary (
             cl_context context,
             cl_uint num_devices,
             const cl_device_id *device_list,
             const size_t *lengths,
             const unsigned char **binaries,
             cl_int *binary_status,
             cl_int *errcode_ret)

If not then please consider enlightening me on this. Thank you.

It seems that the converter is mis-parsing const unsigned char ** and is ignoring the "**" part. (CreateProgramWithSource takes a const char ** and is parsed correctly.)

I'll check this. For the time being I'd suggest adding a DllImport manually, with a #warning that this is a temporary workaround, until the issue is fixed.

Fixed in rev. 2410.

According to cl.h, the correct signature is byte** binaries, while the spec defines this as void** binaries. I'm following the first, as the intent is somewhat clearer and matches Assembly.Load from the BCL (byte arrays which contain binaries).
