- The most common questions and answers regarding the GNU GPL and how
it applies can be found in the http://gnu.org/licenses/gpl-faq.html, if you cannot find the answer there please contact <legal@gnu.org> instead of posting your question on one of the GCC mailing lists.
In addition:
discussions of licensing issues are off topic on GCC mailing lists.
- you should ignore all such discussions, since they invariably include lots of legal-sounding opinions from people who are not lawyers and don't know, and often have significant misconceptions.
- remember that even lawyers don't know what the exact implications of copyright law are, juries often surprise them. So even if you go ask a lawyer, you won't get a definitive opinion.
