Subject: define WINVER as 0x0400 for VC++ 6 because its headers give a warning if WINVER ...

define WINVER as 0x0400 for VC++ 6 because its headers give a warning if WINVER >= 0x0500 is used and are generally broken for higher WINVER values

+        It makes sense to define WINVER as:
+            - either some lowish value (e.g. 0x0302) to not even compile in the
+              features not available in Windows version lower than some given
+              one
+            - or to a higher value than the one used by default for the given
+              compiler if you updated its headers to newer version of Platform
+              SDK, e.g. VC6 ships with 0x0400 headers by default but may also
+              work with 0x0500 headers and beyond
