Proposal: Upgrade compiler version for Windows

[Ivan Krylov]

Phil,

First, I do have a license for VS2003. And more so, one can by vs2003 
for some third party stores, it is just that Microsoft does not sell or 
support VS2003.
The build problem with the compiler version is not my personal one.

There is a good point about figuring out what set of builds/tests could 
be considered comprehensive. There is no JPRT in the open. We do test 32 
and 64 bit builds.
I do not have a solution that would retain compatibility with VS2003. 
And the changes that I have borrow quite a bit of native code in 
windows/native/java/net and awt/java2d for openjdk7. This might have 
impact with regards to bug-to-bug compatibility with existing builds of 
OpenJDK6 for Windows.

Thanks,

Ivan
