'Typedefing' pointers

Hi,

I need to give an alias to the pointer kernel arguments of my kernels as part of a solution I am developing. However, although it is supported in C the compiler gives an error:

error: parameter may not be qualified with an address space

The signature of the kernel is something like:

typedef void* p_void;

__kernel void( __global p_void A)

Isn't this supported by OpenCL? Is there anything I can do?

Thank you.
