bug#1698: 23.0.60; OSX: Wrong type argument: wholenump, -1

[Markus Triska]

On OSX 10.4 with X11, when I do:

   $ emacs -Q -f server-start

and in another terminal do exactly the same:

   $ emacs -Q -f server-start

then the second Emacs instance shows the following error message:

   Wrong type argument: wholenump, -1

When I do M-x toggle-debug-on-error before calling `server-start' in
the second instance, then the Lisp backtrace is (byte-code omitted):

   Debugger entered--Lisp error: (wrong-type-argument wholenump -1)
