LCC https://en.wikipedia.org/wiki/LCC_(compiler) is a nice well written C compiler that has been used in things like quake3. It's a literate progam and there is an awesome book based on it.
It used to be a commerical product but the source is available now, on the other hand it isn't under a free software license so nobody really wants to use it. I feel like it has huge potiental if it were put under a proper open source license.
Does anybody have any ideas how we might be able to get it properly open sourced?
