Yet another OpenJDK7/Windows build story

[Lussier, Denis]

I have to jump thru most all of those same hoops building OpenJDK 6 on
Win2k with VS2003.  Note that building on Linux is much easier and the
build takes less than 20% of the time on the same machine.  Also, in
my experience the Bootstrap jdk must be 1.6.0 Update 10.  I was
originally trying with Update 16 and it errors out building CORBA.
