I redefined the definition of the bk_create function to contain a void **pdate pointer, but that did not really help. Now I get a compiler error:

"Incompatible pointer type passing 'DWORD **' to parameter of type 'void **', so I need an explicit cast each time

bk_create(... (void **)&pdata);

But I think this is better than what we had before so I leave it. Please note that all front-ends using bk_create need to be modified accordingly to suppress this warning.
