As for as license, Emacs is linking against a library that is normally distributed with the major components of the operating system, so that part of the GPL applies. What it is normally distributed thus, the system library exception applies. But it would be good to verify that that is generally true. Do users ever install these libraries separately from the major system components? > What about systems where openssl is not normally present out of the > box? Aren't we encouraging people to install it? Not particularly. The build will work just fine without openssl, and no part of the documentation or installation instructions encourages people to install openssl. This is a red herring. There is nothing wrong with installing OpenSSL. It is free software, after all. As a general matter, we encourage people to install OpenSSL. However, when they install it, the GPL3 system library exception does not cover it. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
