* Kill -
* Simulate Unix kill on Windows/NT and Windows/9X.
* This good enough to support the Berkeley DB test suite,
* but may be missing some favorite features.
*
* Would have used MKS kill, but it didn't seem to work well
* on Win/9X. Cygnus kill works within the Gnu/Cygnus environment
* (where processes are given small pids, with presumably a translation
* table between small pids and actual process handles), but our test
* environment, via Tcl, does not use the Cygnus environment.
*
* Compile this and install it as c:/tools/kill.exe (or as indicated
* by build_windows/include.tcl ).
