title: ./configure on Cygwin hangs when "checking for a BSD-compatible install..."
body: <p>I use Cygwin in Windows 7 and try to compile a library, <a href="https://github.com/zeromq/zyre" rel="nofollow">Zyre</a>. My 'configure' file was generated automatically by autoconf. When I run <code>./configure</code> from command line for makefile generation, it just says</p>
  
  <pre><code>checking for a BSD-compatible install...
  </code></pre>
  
  <p>That is it. There is no errors, no complaints, nothing. I waited >1h and also tried to restart a few times.
  What can be wrong? What can I do to make it work?</p>
  
  <p><strong>Here is some background information about the platform I use:</strong></p>
  
  <p><code>which install</code> gives <code>/usr/bin/install</code>.</p>
  
  <p>The file <em>config.log</em> after interruption is:</p>
  
  <pre><code>This file contains any messages produced by compilers while
  running configure, to aid debugging if configure makes a mistake.
  
  It was created by libzre configure 1.0.0, which was
  generated by GNU Autoconf 2.69.  Invocation command line was
  
  $ ./configure 
  [..]
  install_sh=''
  [..]
  </code></pre>
