I don't follow, I'm sorry. OpenBSD has never used GNU libc. The BSD projects have long developed their own C libraries.

The clang compiler is a part of the LLVM collection, it is not derived from gcc at all.

As for GCC, The GNU project changed the license for their compiler sometime after the 4.2.1 release to the GPLv3. Meanwhile, up until the Clang 9.0.0 release, Clang was developed under a permissive license (NCSA). We're facing a similar problem now with LLVM/CLang, with their re-licencing to the non-permissive Apache 2.0 license.

How is Apache non-permissive? It deals with more things (like patents) and it's a bit complex, but it's not viral I'm pretty sure.

Ah. Whatever. The common meaning of "non-permissive" is "copyleft", not "has patent clauses the OpenBSD project has weird concerns about".
