Unable to connect on PowerPC64

[Mingcong Bai]

I was not able to connect a SFTP/SCP server on a PowerPC64 Linux, the error shows:

Status: Connecting to nnn.nnn.nnn.nnn:nnn...
Status: Connected to nnn.nnn.nnn.nnn
Error: unable to understand SFTP response packet from server: request ID mismatch
Error: Could not connect to server
Status: Waiting to retry...
Status: Connecting to nnn.nnn.nnn.nnn:nnn...
Response: fzSftp started, protocol_version=7
Command: open "nnn.nnn.nnn.nnn" nnn

Error: unable to understand SFTP response packet from server: request ID mismatch

The same version of FileZilla, linked against libraries of the same versions worked fine on ARMv7, ARMv8, AMD64.

There seems to be a type mismatch with some implicit pointer casts in PuTTY. Please try compiling FileZilla with this experimental patch.

Yes, the patch indeed fixes the issue.
