Walter, what I've found is when compiling to squid 3.5.x and higher, the
compile options change. Also remember that many of the options that were
available with 3.1.x are depreciated and likely will not work with 3.4.x
and higher.
The other issue is that squid is only supposed to be handling HTTP and
HTTPS traffic, not FTP. trying to use it as a FTP proxy will need a
different configuration than the standard HTTP/Secure proxy.
