title: Cygwin - Squid make errors
body: <p>I did a full installation of cygwin on a windows server 2008 r2 and I downloaded the Squid3.4.4 source. I ran the ./configure [options] command and then the next step is to Make and install squid.</p>
  
  <p>When I run make I get a ton of errors. Here is a sample of what I am seeing:</p>
