Thank you so much for your efforts! I will try to download your
patches this afternoon on a roommate's Windows computer, and try to
see if I can fix the remaining tests.

Thanks!! Since adding GC support took about 10 lines of C++ code, I
guess it won't be hard to switch to a different system.. I'll try and
see if I can add support for a version that works with Win98..

BTW if anyone is interested in running Shed Skin under OSX.. I got
this comment on my blog (http://shed-skin.blogspot.com)

(why doesn't everybody just run Gentoo? :P)

>Wow, very cool. Congratulations!

>Here's what I had to do to get it working on the Mac (OS X 10.4):

>1. Install the garbage collector from

thanks!
