"cc" isn't POSIX, since over a decade I think.  "c99" is POSIX, and it is
a shell script calling whatever "gcc" is first in the PATH, on most distros.

Many scripts that call "cc" expect to find a K&R compiler, historically at
least -- maybe all such scripts went the way of the dodo, that wouldn't be
so bad.

I don't know about "c++", and it is pretty much impossible to search for.
Jeff added it in <https://gcc.gnu.org/r34527>, maybe he can clarify?  But
that was quite some time ago ;-)
