Hello Monty,
I think this solution inadequate, it will be difficult to
maintain.
E.g. if we want to re-structure the client
implementation in future -- by moving out common members, or,
say, merging common parts of MYSQL_STMT and MYSQL, we won't be
able to do that without breaking the ABI again.
I believe we should pay the price and replace all structures with
opaque pointers.
