Is this correct? No, that's entirely incorrect. The runtime exception doesn't distinguish between static linking and dynamic linking, and neither does the runtime exception, as clearly stated in its FAQ: "neither the GPL nor the GCC Runtime Library Exception distinguish between static linking, dynamic linking, and other methods for combining code in their conditions. The same permissions are available to you, under the same terms, no matter which method you use." https://www.gnu.org/licenses/gcc-exception-3.1-faq.html
