      The projects provided for zlib1.2.7 support 64 bit builds, however it didn't
      work cleanly for me.  They use different projects for VC9 and VC10.
-     They don't provide support for VC8 or 11beta.
+     They don't provide support for VS2005 or VS2012beta
 
      I have created build environments for zlib and expat within exiv2/msvc.
      I don't include the source code for zlib or expat - only the build environment.
