Yes, that's correct. I mentioned the y.tab.c copyright notice of Solaris Yacc mainly to point out that it's clear that Sun is making a copyright claim in this area. I mentioned the Berne convention because not every country is a signatory, and in non-signatory countries like the Cayman Islands my analysis of what's permitted might not be correct. > I don't know what the default status is of works produced by X's use > of Y's copyrighted programs, but I rather suspect that such products > belong to X It depends on whether the produced works are "derivative works" of Y's copyrighted programs. For many programs (e.g., "cat") it's quite clear that the program's output is not a derivative work of the program. But in the case of Yacc, it's pretty clear that the C output file is a derivative work of both the Yacc template file and the user's source file. So, legally speaking, the user and Sun both have copyright interest in the C output file, and you need permission from both parties before you can redistribute that file. _______________________________________________ Help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
