bug#59135: Receiving large files with ERC-DCC

[Tohiko Looka]

When receiving large files with ERC-DCC I get  the error

ERC-DCC (erc-pack-int): packet too large

incessantly which makes Emacs unresponsive until eventually the IRC
server connection is closed.

I believe this happens when the file size is larger than 2 or 4 GB
which does not fit in an integer.  This causes a failure when the
function erc-dcc-get-filter tries to send back the number of received
bytes.

Is there a way around this?
