Define "complete Hotspot and J2SE code".
Just OpenJDK?
Was this the JRL or full Sun JDK sources?
Just hotspot and j2se (or now called "jdk") directories?
Just installing an Express compiler and using it doesn't mean that
during the build the Professional files installed on the machine
are not used. To know it works, you have to start with a clean
install of the OS and Express.
Hotspot certainly could be built with the Express compiler, and
I suspect much of the OpenJDK if not all of it right now can be
built with the Express compiler.
But there are parts of the Sun JDK sources that use ATL and cannot be
built with the Express compiler.
It's not clear if and when those sources might end up in the OpenJDK.
If you can use the Express compiler for your OpenJDK work, that's great,
just make sure that's indeed what you are using. ;^)

About a year ago I did build the complete Hotspot and J2SE code using
VS2005 Express + MS Platform SDK + DirectX SDK - all downloaded for free
from the Microsoft web-site. During building I identified some bugs (to
name a few: 6486546, 6488751, 6523947). Some of them belonging to the
J2SE code I've fixed myself, some were fixed by the Hotspot team. AFAIR,
apart from the problem with the manifest files (see 6523947) I don't
recall any unresolved issues... Are there any?

We are focusing on the Professional edition first because the free
Express edition does not include the ATL include or lib files.
I'm not an ATL expert, but JDK builds have a dependence on it and it's
probably not going away for quite some time I'm told.
It's quite possible that much of the OpenJDK is very buildable with the
free Express edition, and once we are building with the Professional
edition, someone can see how much is buildable with the Express edition.

I certainly can't speak for Sun on this. But, I don't think there
is any immediate plans to use GCC on Windows. It would probably be
OK if someone wanted to try, but I can't imagine it being even
remotely easy. There's just so much stuff dependent on the various
Visual Studio or MS SDK header files, that I'm almost positive you
have to install them to do the build, so why bother with GCC? (even
from a Free Software point of view, if you can't get away from the
proprietary MS SDK/VisStudio, then compiling with GCC rather than
the MS-provided one isn't going to be really any win at all).
Indeed. But we should make it possible to use the free versions of
the MS Visual Studio at least.
