[Coin-symphony] unresolved external symbol

[Ted Ralphs]

It appears as though the .dsp file for Osi is out of date. The files 
OsiAuxInfo.cpp and OsiAuxInfo.hpp were added to the repository recently 
and do not seem to be referenced in osiLib.dsp. Therefore, the 
OsiAuxInfo class is not part of the library, as it should be. It should 
be easy to add these two files to the project. I have cc'd JP Fasano, 
who maintains these project files to let him know, but you should be 
able to do the update yourself in the meantime. Please let us know if 
this fixes the problem.

Cheers,

Ted
