 You don't need to build these projects yourself. You can download the

-Build instructions
------------------
- Unzip zlib*.zip and copy the files from contrib\vstudio\vc7,
-  from contrib\vstudio\masmx86 and from contrib\minizip into the same
-  directory.
+Build instructions for Visual Studio 7.x (32 bits)
+--------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
 - Download the crtdll library from
    http://www.winimage.com/zLibDll/crtdll.zip
-  Unzip crtdll.zip to extract crtdll.lib.
- If you are using x86, use the Release target.
- Open zlibvc.sln with Microsoft Visual C++ 7.0 or 7.1
+  Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
+- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
  (Visual Studio .Net 2002 or 2003).

+Build instructions for Visual Studio 2005 (32 bits or 64 bits)

+- Uncompress current zlib, including all contrib/* files
+- For 32 bits only: download the crtdll library from
+    http://www.winimage.com/zLibDll/crtdll.zip
+  Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.

+----------------------------------------------------------------
+at the time of writing this text file, Visual Studio 2005 (and 
+  Microsoft Visual C++ 8.0) is on the beta 2 stage.
+Using you can get the free 64 bits compiler from Platform SDK, 
+  which is NOT a beta, and compile using the Visual studio 2005 IDE
+see http://www.winimage.com/misc/sdk64onvs2005/ for instruction

+- Uncompress current zlib, including all contrib/* files
+- start Visual Studio 2005 from a platform SDK command prompt, using
