[Coin-discuss] XPRESS OSI updated.

[Matthew Saltzman]

A new version of the XPRESS solver interface (rev. 1.11) has been pushed to 
CVS.  This revision fixes several issues related to the OSI unit test, 
including:

- tracking constant objective offsets
- returning NULL for empty rim vectors
- interaction with CoinPresolve

Other issues fixed:

- compiles warning-free with gcc4
- properly returns MIP solution after branchAndBound()
- some internals

A few issues remain (mostly the DeSmet test units), but I am pleased to report 
that the unitTest now runs to completion without crashing.
