Those two structures have the same size and the same field offsets.
Would you thumb your nose at a conversion of the style

aclXXX( __aclent16_t * acl)
  __aclent32_t * acl32 = acl;
  acl32->a_id &= 0x0000FFFF;
  return (whatever) aclXXX32(acl32);
or would you insist on alloc and copying of everything
before and after calling the aclXXX32 function?
