Hi Don,

To answer your question, yes, I did hear about templates, and the previous tips should have shown you that.

You are right, this solution does not work for templates. However, should it be implemented for templates, the code would look much more complicated, and there are many problems with different compiler vendors.

Having the EXTERNAL_OPERATOR_* macros in place, and with some good knowledge of templates, you should be able to implement them yourself.

Best,
John
