That's a bug. You'll notice that if an exception is thrown in 
main() (or anything called from it), you'll get a MessageBox for 
GUI applications. That this doesn't also occur with unittest 
failures is a bug.

For now, you can work around this by writing your own WinMain, 
which calls rt_runModuleUnitTests explicitly, inside a try/catch 
block which will then display a MessageBox.
