   The problem is that there are no contents under the machine/i386
   directory.

Thanks.  i386/setjmp.S is in our source tree but it didn't make it into
1.8.0.  I'll fix that.

   I can provide a patch for both this and the i960 problem if
   someone will just let me know.

I'll have to get back to you on this.  I don't know that the
state of machine/i960 is.
