title: unfound entry point deflateSetHeader at zlib1.dll
body: <p>I'm trying to install GTK+ 2.16, using Code::Blocks, I set the "gtk" environnement variable and everything. It compiles successfully, the problem rises in run-time when it says "No entry point found for procedure deflateSetHeader in the dynamic library zlib1.dll".</p>
  
  <p>Anyone has an idea about this ? Is this some kind of bug that should be reported ?</p>
  
  <p>Thanks in advance</p>
