[omniORB] Debug Assertion Failed! Problems with 2.8.0 and Visual C++.

[Sai-Lai Lo]

Debug version of a program should be linked with the debug version of the
runtime libraries:

omniORB280_rtd.lib omniDynamic280_rtd.lib omnithread2_rtd.lib

If you have not done so, please read README.win32 on building projects
using omniORB2.
