[Xsb-development] Foreign intf for OS X

[Terrance S. <ts...@cs...>]

As noted, it works.  I'll hold off for a few days on integrating my
changes until Rui finishes his integration of the multi-threaded engine.

The only issue is that the configure script needs to be able to associate
FOREIGN_ELF with OS X.  Barry sent a patch that defines FOREIGN_ELF as 1
in the nether regions of the configure script -- but we should probably
make the association in configure.in (or some other upstream file).  Can
Michael or some other configure guru help out with that change to save me
some head scratching?

Thanks,

	Terry
