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

[Mike Bendickson]

Update.  The release version does work from the command line also.  My fault
on that one.  My only problem now is the debug assertion failure with my
debug build.  Did I mention that I'm using VC++ 6.0?  I had to copy the
mscvp50.dll and mscvp50d.dll files from another system.

Here are the libraries that I'm using for my Win32 console appliction.
Debug build:

kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib
shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib
shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib
omniORB280_rtd.lib omniDynamic280_rtd.lib omnithread2_rtd.lib

These are all defaults, except for the omniORB libraries at the end of
course.

-Mike
