Ohh I see, txn_count is not included in the PoW hash computation...

Wouldn't be a lot more helpful if the returned headers contained the correct txn_count field so receivers could validate the block PoW before requesting the full block?
This doesn't have anything to do with the POW.

The wiki https://en.bitcoin.it/wiki/Protocol_specification#Block_Headers says that in response to getheaders, nodes send block headers with the field  txn_count set to zero. The code seems to agree.

Thanks, Sergio.
