Looks like I wasn't paying attention.  A diff with the proper slashes is
attached (let me double check, looks correct).

Actually thats what I thought the first time I saw a fsext -- how on earth
did you guys get the first argument in the va_list?  From
src/libc/dos/io/_open.c:
  if (__FSEXT_call_open_handlers(__FSEXT_open, &rv, &filename))

My understanding of whats going on is that va_list is simply a void* that
points to a position in the stack; the &first_argument_name gets that
position, just like a va_start.   DJ is probably the best authority on the
subject.
