Yes. We don't need c++ to bootstrap g++ or anything else in the base system. Once we build the compilers, we can build the c++ that's in the tree. While technically true, that c++ (the binary) is not needed, our g++ requires gperf(1) to build, which is written in C++. So we need gperf + C compiler to bootstrap. How the gperf binary comes into existence on the host system is someone else's problem :) however that means that FreeBSD can never get rid of gcc. so clang can never become the main and only base compiler. Not quite true, right now the host system (whatever that is) needs a working C compiler plus a whole lot of other stuff. With clang the host system needs a C++ compiler + lots of other stuff. I haven't tested any other compilers, but gcc and/or clang might also build with the Sun compilers, for example.

Log:
Complete WITHOUT_CXX support. It implies WITHOUT_GROFF and
WITHOUT_CLANG.
is there no way to build clang/llvm without CXX support?
cheers.

Don't build clang bootstrap/build-tools depending on this flag. We also
keep gperf, devd and libstdc++ around to prevent foot-shooting and to
make this a two-way street.
