This produces the following warnings/errors and found the bug
fixed in the previous commit:

 librpc/gen_ndr/ndr_misc.c:851:15: error: cast between incompatible function types
   from ‘enum ndr_err_code (*)(struct ndr_push *, int,  enum netr_SchannelType)’ to
   ‘enum ndr_err_code (*)(struct ndr_push *, int,  const void *)’ [-Werror=cast-function-type]
   .ndr_push = (ndr_push_flags_fn_t) ndr_push_netr_SchannelType,
