Hi,

I've committed the attached patch which adds some declarttions needed by 
ports using the new parallel write support. Tested on an internal port. 
No effect on existing ports.

	* sid-cpu.scm (-gen-scache-semantic-fn): Generate a declation of 'written'
	if with-profile or with-parallel-write.
	(cgen-semantics.cxx): Make the @prefix@ namespace available if with-parallel.
	* operand.scm (op:new-mode): Convert (obj:name op) to a string for
	string-append.
