NO mention was made about gcc being absent, and I am uncomfortable with taking that step yet. Having gcc just present, will not hurt you.. even after it is gone we will need to support those who will be replacing clang with newer versions of gcc in hteir own products. The plan is not to delete gcc from the tree, it is to disable building gcc by default when clang is the system compiler. If you are building products then you are perfectly at liberty to set WITH_GCC=yes in your src.conf. Our gcc is from 2007. It has no C11, no C++11 support. It has bugs in its atomic generation so you can't use it sensibly without lots of inline assembly (which it doesn't support for newer architectures) for multithreaded things. Our libstdc++ is ancient and doesn't work with modern C++ codebases. Putting them in the base system means that people will use them. If anyone wants them to remain, then speak now and this will be taken as your volunteering to: - Maintain our forks of both gcc and libstdc++ - Handle every single PR that is filed by people using these If you are willing to do this, then that's great. If not, then you are asking other people to support ancient codebases that they are not using.
