The CLISP/Win32 returned -1.

If this causes a problem, please tell me and I can change that. Possibly processes will not be interruptible. clisp >2.33.2 should work. I appreciate it when new code still works with old versions of other programs.

Well, the idea behind getpid is that Emacs can send a SIGINT to that
process to interrupt it.  That ideas does apparently not work so well
on Windows but it certainly will not work if getpid returns -1.

I guess SIGINT is not the Windows way and something else should be
used instead.
