Ah, ok. configure was built with apple's version of gnu libtool on tiger
or panther.
Change the sed to match ${_S_}nmedit instead of ~nmedit and it should
have some effect on the link line.
The symbols that are private extern should still be available to all the
objects in the library itself, so returning the address of osx_about
should work.
