title: Pascal Delphi - Undeclared Identifier
body: <p>I'm using the Synapse library in a Delphi project to do some networking.</p>
  
  <p>When I try and use one of the Types that are defined in the external units, i.e: 'TTCPBlockSocket', it has the red underline and says "Undeclared Identifier 'TTCPBlockSocket'".</p>
  
  <p>The files are all in the correct folders and the 'uses' statement can find them and shows no errors.</p>
  
  <p>The strange thing is that I've had an identical setup in another project and there have been no errors in that project.</p>
  
  <p>As a note: I can't install/edit the software/settings, so I can't add any fixes.</p>
