My proposal is platform independent (i.e. it will work also under Win32,
OS/2, etc., without any changes). Your proposal probably requires starting
the compiled binary using platform specific API functions to run it with a
modified environment rather than using ExecuteProcess which results in
passing the standard parent's environment (changing the current's process
environment may not be supported on all platforms).
