To take a real example from the existing drivers, that works with
typedef struct apr_dbd_prepared apr_dbd_prepared;
struct apr_dbd_prepared {
const char *name;
int prepared;
};
but fails with
typedef struct apr_dbd_prepared apr_dbd_prepared;
typedef MYSQL_STMT apr_dbd_prepared;
IOW, removing the #ifdefs would force drivers to wrap everything,
even if they have no good reason to do so. KISS!
