unused parameter warnings

[alex@…]

There's a few methods which produce 'unused parameter' warnings and prevent having warning be treated as errors.

I'm attaching a patch that fixes the ones that I've found.

Two comments:

1) You should create two tickets, one for spirit and one for tokenizer, and assign them to the maintainers of those libraries. That will help bring them to their attention. Bugs submitted against "boost" (no component) are likely to be missed.

2) A better way to silence these warnings is to "not name" the parameters.

Instead of:

grammar_helper_list& operator=(grammar_helper_list const& x) 
	{   // Does _not_ copy the helpers member ! 
		(void) x; 
		return *this; 
	} 

You should write:

grammar_helper_list& operator=(grammar_helper_list const&) 
	{   // Does _not_ copy the helpers member ! 
		return *this; 
	}

Both comments make sense. I will report two separate bugs in their respective projects and modify my patch according to the suggestion #2 above. Thanks!

Thanks. I'm going to close this bug, and wait for the next ones.
