Summary: Patch for kvm_code on FreeBSD 5 to allow running without /proc
Original Submission: The KVM code used by FreeBSD to read argv and envp requires
/proc to be mounted for the envrionemtne to read properly.
This is not true by default on FreeBSD system of 5 and above.
The attached patch alters the code to always use the static
environment pointer on FreeBSD, even when using KVM. This
allows the code to work properly on FreeBSD 5, whilst also
working on previous versions.

If we check kvm_getenvv at runtime then it will always produce an error to stderr when
it fails. There seems to be no way of suppressing this - and I dont think its goot to
have code producing errors every time it runs. Thats just going to lead to umpteen
questions and bug reports.
If we check to see if it works at compile time and set an approrpiate #ifdef then we
have a situation where code compiled on an earlir FreeBSD system will not run on a
later system - which breaks backward compatibility in a very bad way. It also means
that code compiled on a FreeBSD system with /proc mounted will not then run on other
systems where it is dismounted... again a very bad thing as a lot of developers
(myself included) run our development systems with /proc mounted as standard.
I didnt like the idea of the #ifdef FreeBSD ether - but as it stands the kvm code only
works properly on FreeBSD anyway, so it didnt seem too much of a loss. We could go for
the option of always using environ though. I think that is always supposed to work
everywhere... whatever you think is most portbale really

it seems a shame to use #ifdef __FREEBSD__ if we could have the problem on other
systems. Why not just check if kvm_getenv works, and if not, use the environ variable?
In fact, maybe we should just always use the environ variable since that should work
everywhere?
