- * @todo DARN! DARN! DARN! Who forgot to do the 32-bit hack here???
- *       FIXME! XXX!
- *
- *       We will now have to carefully check how our compilers have treated this
- *       flag. If any are compressing it into a byte type, we'll have to check
- *       how the request memory is initialized. If we are 104% sure it's ok to
- *       expand it, we'll expand it. If not, we must redefine the field to a
- *       uint8_t and a 3 byte padding.
