+<b>BEGIN WARNING</b>: At this time (Spring/Summer 2010) JDK 7 is starting a transition to
+use the newest VS2010 Microsoft compilers. These build instructions are updated
+to show where we are going. We have a QA process to go through before
+official builds actually use VS2010. So for now, official builds are
+still using VS2003. No other compilers are known to build the entire JDK,
+including non-open portions.
+So for now you should be able to build with either VS2003 or VS2010.
+We do not guarantee that VS2008 will work, although there is sufficient
+makefile support to make at least basic JDK builds plausible.
+Visual Studio 2010 Express compilers are likely to be able to build all the
+"open" sources, with only small adjustments, but this has yet to be made
+to work. Also we have not yet seen the 7.1 Windows SDK with the 64 bit
+compilers. <b>END WARNING.</b>
