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=3Dyes 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.
