I will support it too.

It is a win32 program; I have not tried to add win64 support yet.

I looked at (chibi test) when I started writing tests, but I did not see 
a way to test for syntax violations. For example, I wanted to have test 
that (lambda (x x) x) raises an exception. If (chibi test) can do that, 
I would happily switch to using it.
