This is traditionally fixed in IDL by simply having two pointers in the
IDL, where the top one is a ref pointer (which is not encoded on the

uint32 **foo; 

would be the same as 

uint32 *foo;

I'd favor this approach as it is compatible with the IDL used by the
other compilers and it makes sure the IDL and C interface are the same.

I've just made pidl warn about top-level pointers that are not ref
pointers (these are not even possible in standard IDL).

Would it be ok if I revert your change and fix this in the IDL instead?
