`display-buffer-in-previous-window' should be alright in the present
case - after all you want to show *gud-foo* in the window it was shown
before.  What we have to find out is why `display-buffer' doesn't
replace *scratch* by foo.c in what you describe as:

  At this point, notice that *gud-foo* buffer is gone, as foo.c has
  replaced it.  At some point in time in the past, foo.c would end up
  replacing the other window (the *scratch* buffer).

So why did foo.c replace *gud-foo* in its window and not use the
*scratch* window instead?  Please try to find out.

Thanks, martin
