I can't confirm this other than to say, that I compile stable 9 base
(kernel + world) using clang
and ports using gcc. I have to compile base using WERROR= and
NO_WERROR= settings
in make.conf so that the compilation doesn't halt on error messages.
Maybe this is no
longer required.

This is as per wiki, though admittedly, as per wiki a couple of months ago.

I can imagine that the problem will be compiling ports with clang.
Some of the gcc code is not
correct as per specification. There's a list somewhere of currently
compilable ports using clang.
