[slim-vim] kill(2) for Windows

[Larry Clapp]

Greetings.  Trying to compile Vim+ECL for native Win32, Brad's
cl_vim_kill_int() doesn't compile, because Windows doesn't have a
kill() function (or possibly I'm just stupid and haven't found the
correct include file).

So, if you know how to do what kill does (on Unix) on Windows (i.e.
terminate a process or test if it still exists), please speak up.  I
Googled around a bit and found several ways to *catch* signals but no
way to *send* them.  (Or, again, maybe I'm just stupid.  :)  I'm using
Microsoft Visual C++ 8, aka (I think) Visual Studio 2005.

(I #ifdef'ed out that code and got a clean compile, so I'm pretty
close to having a good Vim/Win32 to post.)

Thanks!
