As someone who is involved with C++ standardisation and so periodically hears
things from WG14, my impression is that the people who care about the things
that you list have all moved to C++, […]

...
In one experiment, I wrapped the C-code in:

	#ifdef __cplusplus
	extern "C" {
	#endif

and compiled it with a C++ compiler.

Given that we have tried to dial code quality to 11 in Varnish, the
number of relevant observations by the C++ compiler was a devastating
indictment of how badly the C language has been let down by it's
stewards.

I'm not saying FreeBSD should think along the same lines, but FreeBSD
should totally think along those same lines:

Even if we stick with pure C-code, the C++ std-people have a much
more sane approach to it's proper compilation that the C std-people.

And there are nice features in C++ which do not make the source code
unreadable.
Second this.

Not surprised...

I have done this as long as C++ as been around and it always made for better code in the end.

Truly, this is one of the easy things that could be done with FreeBSD code, and probably would help quite a bit improving the code.
