Linus wrote a new POSIX kernel. He did not "port" any form of the
existing Unix kernel. (There were already real Unixes (that is,
descendants of the v7 codebase) that were ported to the x86 when Linux

It started in the early or mid-1980s (I forget which) as "C with
Classes" and then evolved (or some might say metastasized). Originally
it was implemented with a preprocessor in front of C (appropriately
enough called "cfront" IIRC), though the first direct implementations
showed up by the early 1990s.

I'm not a fan of C++. Many other old Unix hands are also not fans. C++
is sometimes a necessary evil, but it is rarely a pleasure.
