in thread Am I Allowed to Make a New Compiler/Language using Perl?
I think the GPL v3 comes close, or at least forces restrictions on the (distribution of) the output generated by a GPL v3 program. But I have solved this problem for me personally a long time before the GPL v3, so I haven't investigated whether that is really the case for things like a compiler. It seems to be the case for things like web application servers, where accessing the application over the web is basically identical to distribution of the application server binary.
