Actually, it looks like 4-UH did include source code - my apologies Yon, I must have been thinking of something else.
I'd be happy to submit the patches I have, but I should clean them up first. Currently they are just in my HEAD checkout and not against a tagged release. There are also a few places where I did quick and dirty things that would break non-Win32 installs, and I need to come up with better solutions for those.
