The WIN32 package is not needed anymore in newer #+win32 clisp, since sys::process-id is now always present on UNIX and Win32.

Thanks. Committed.

On a related note, would it be useful to have a comment in the source about what interfaces need be defined (e.g. getpid) and which are there for nice functionality only (e.g. stepping)?

I guess it would be useful to say which interfaces are needed for which features. Such comments would be nice to have but not essential. You can always invoke a command and see if something breaks :-) Helmut.
