title: "win32" vs "win64" for osgi.os property
body: <p>I have Win7 64 bit OS on my machine. I was working on creating a 64 bit plugin in eclipse. I was trying to set value for osgi.os property. I referred this <a href="http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fua_dynamic_filters.htm" rel="noreferrer">link</a>. </p>
  
  <p>The link mentions </p>
  
  <pre><code>Property    Meaning                   Possible values
  osgi.os     operating system          win32, win32, linux, macosx, aix, solaris, hpux, qnx
  osgi.ws     windowing system          win32, motif, gtk, photon, carbon
  osgi.arch   processor architecture    x86, x86_64, ia64, ia64_32, ppc, PA_RISC, sparc
  </code></pre>
  
  <p>I was wondering for osgi.os options it has no mention for win64 as a possible value. If I have win64 OS in my machine what value should I assign to property osgi.os as it only shows win32 as possible values for osgi.os property?</p>
  
  <p>And for osgi.os property why does it repeats win32 twice as possible values? For osgi.os property are there any reason behind mentioning <code>win32, win32</code> twice instead of just mentioning <code>win32</code> only once?</p>
