Summary: link_objects in setup.cfg crashes build

Initial Comment:
When I put the following into setup.cfg:

---

[build_ext]
include_dirs = /home/mschatte/myPackages/XSB/config/i686-pc-linux-gnu:/home/mschatte/myPackages/XSB/emu
link_objects = /home/mschatte/myPackages/XSB/config/i686-pc-linux-gnu/saved.o/xsb.o

---

in order to link a c extension to another object which should reside on the users computer, I get the following error (tested on two kubuntu machines, python 2.4):

# python setup.py build

maybe it isn't a bug, but link_objects is not well documented, so I wasn't able to find the appropriate syntax for setup.cfg
