On the other hand these tools are perfect for building FreeBSD kernel and base. Extrapolating my experience with base GCC I am very confident in it as a FreeBSD development tool. Extrapolating my experience with Clang I am not yet confident in it as a FreeBSD development tool. I do not care about C11, C++11 and modern C++ codebases. I care about what's in /usr/src and what gets compiled by buildkernel/buildworld. That's just me, of course. But, OTOH, those who care modern C++ codebases should be perfectly capable to install a compiler from ports or switch to clang as their default compiler. -- Andriy Gapon
