How many changes were necessary to do this? Was it mostly a matter of
working out instructions to get MSVC to work, or did you need a lot of
changes to the R source code? Does your version pass make check?
I don't use that compiler, so I can't test any of your changes. I'm
not interested in maintaining multiple compiler targets, but if it's
easy, I'd consider it (or at least try to avoid doing things that will
make it hard for you to do it).

That should be put together as a package.

In your minor extension I, could you submit a bug report showing how
to invoke the bug, and how to fix it? There's still time to get this
Could you write up a description of why the changes in II and III are
a good idea? I'll put them into 1.8.0 if they make sense.
Re the suggestion for a global "dont_exit" flag: My first answer is
that global flags are bad, we have way too many of them now. What we
need are bigger changes that make all of our global flags unnecessary.
