I retrieved this, unzipped it into c:\winclisp and then tried
running c:\winclisp\clisp.bat in Windows95, but I got:

   Cannot find /bin/sh.exe, copy /usr/bin/bash.exe to it!
   Cannot find /usr/bin/sh.exe, copy /usr/bin/bash.exe to it!

   *** - UNIX library error 2 (ENOENT): no such file or directory

Any ideas on how I can fix this?

Sorry, I don't understand this. Do you mean that it is possible to call
external C functions without recompiling the lisp? If so, how can I do it?

Another question:

4. Is it possible to run the DOS version of CLISP under Windows95? Do I
   have to use RSX to do this? What properties do I need to set so that I
   don't get the "DPMI not supported" message coming up?
