Wiki about GNUstep and friends.
- Configure GNUstep-Make to use the non-fragile ABI. CC and CXX should be clang and clang++, respectively
- Remove dependency on GCC, use system clang (or clang port if not available) with libobjc2
- Find gnustep ports that don't work with the non-fragile ABI and either:
- Fix them, or
- Import newer versions (e.g. from GAP)
- Clean out ancient ports (e.g. old versions of Étoilé frameworks and earlier)
