If it is only the transport that needs to be protected, you could use
scp (or sftp or ftp over SSL). Otherwise, maybe consider rar as you can
get a version of rar for Windows and Unix made by the same company (and
so you should have a higher chance of things working). Or install the
windows compiled version of gcc.
