In that case I'd prefer at this point to leave the the symbol-file 
passing out.  Instead just stick to a single simple qSymbol packet.  The 
behavour would be:

	To start a transaction sequence:

		-> qSymbol

	It could even be:

		-> qSymbol::

	If you want simplicity and consistency.

	The reply would be as you proposed:

		<- ""
			Not recognized
		<- "OK"
			Recognized but not now
		<- <the-I-want-a-symbol-address>
			As you've described

	From then on it is:

		-> qSymbol:<addr>:<symbol>

I don't think it is a good idea to try to include a mechanism for 
passing back and forth the name of an object file until there is a 
demonstrated need for such a feature.

The reason for this is that, in the past GDB has incorporated what look 
like very reasonable idea's only to find that, when someone uses them, 
they are insufficient.
