#172 compile warning "assignment operator could not be generated"

[Andrey]

I created my unittest application based on HostApp
example and receive the following warning during
compilation.

It appears that something goes wrong during compilation
and it does not generate assignment operator.

I suspect this warning can be the reason of very
difficult error.

Please, clarify and fix.

c:\Sources\Sources\external\cppunit\include\cppunit/extensions/TestSuiteBuilderContext.h(121)

warning C4512:
