[sldev] PowerPC weirdness continues

[Paul TBBle Hampson]

OK, I've been trying to work out why my local PowerPC build
is stuffing up, yet at least one person has got a working
PowerPC build on this list...

Looking at ParcelOverlay again:

{
    ParcelOverlay Low Trusted Zerocoded
    {
        ParcelData      Single
        {   SequenceID  S32             }   // 0...3, which piece of region
        {   Data        Variable    2   }   // packed bit-field, (grids*grids)/N
    }
}

Based on my understanding of the packet format, I'm expecting

XX YY YY YY ff ff ZZ ZZ SE QU NC ID DL EN DATA...

Where XX is flags, YYYYYY is BE packet sequence number,
ZZZZ is the message ID for ParcelOverlay, SEQUNCID is the
value for SequenceID, DLEN is the LE length of the following sequence
and then DATA... is the data.

Going from the dumped packet at the end of this email:
40 00 00 0e ff ff 00 e4 00 04 c1 c1 81 81 c1 81 

Sequence #0x0e (the next two were 0x0f and 0x10, so that's OK)
ZZ = 0xe4, that's fine.
Then I get the 2-bytes I expected for DLEN, (the other packets concurred)
which is bizarre, since I'm expected four bytes of sequence ID here.

1024 bytes of DATA follow, then four null bytes.

So the length (1038) is correct for what I'm expecting.

So, unless I'm missing something important, this packet dump is actually badly broken. >_<

Oh well. Something else going wrong, earlier in the process. I've got to get a dump of the
packet at the various stages it progresses through, see where the buffer's being broken, and
if it's related to my problem.

Here's the dumped packet: (The packet dump output could do with a once-over with the
pretty-brush, BTW. ^_^)
