template class instantiation as default argument

[Frank van Viegen]

g++ 3.3.5 is unable to use instantiations of templated classes with more than 
one template argument as default arguments of class methods. Not sure if I've 
got the terminology right here, so please have a look at the example code 
below. It shows 4 very similar function/method declarations, of which only 
the last one fails to pass the compiler.

Thanks,
