re PR c++/19966 (Misleading message "must take exactly one argument")

Browse Source 
2005-03-17  Paolo Carlini  <pcarlini@suse.de>

	PR c++/19966
	* cp-tree.h (grok_op_properties): Change return type to void.
	* decl.c (grok_op_properties): Return early - don't check the
	arity - in case of a static member or an operator that cannot
	be non-member; tidy a bit.
