[Dip] Problem running the GAP example

[Ted Ralphs]

I fixed the problem with the GAP example in stable/0.9. It should work out
of the box now if you grab the latest in that stable branch. There may be
other examples that need similar fixes and I haven't done that yet.

I made some related fixes in trunk, but something is wrong there---the same
instance does not solve in the root node as it does in stable. I'm checking
into it.

Cheers,

Ted
