  <p>As you can see I do have gpg-error installed, or so it seems.
  Perhaps the problem is that the source directory is on F:\ while Cygwin, Windows and everything else are on C:\?</p>
  
  <p>I've found the same question asked before on <a href="http://lists.gnupg.org/pipermail/gnupg-users/2009-May/036486.html" rel="nofollow">http://lists.gnupg.org/pipermail/gnupg-users/2009-May/036486.html</a> -- unanswered...</p>
  
  <p>Cygwin 1.7.31, Windows 8.1 x64, libgcrypt-1.6.1 and libgpg-error is 1.9, naturally.</p>
  
  <p>Thank you in advance, please tell me if I should provide additional information.</p>
