2004-11-09  Joseph S. Myers  <joseph@codesourcery.com>

	* objc-act.c: Use %q, %< and %> for quoting in diagnostics.

	* objc-act.c (objc_lookup_ivar): The new OTHER parameter
	contains the result of the ID lookup by the C or C++
	front-end; in class methods, use OTHER if it exists;
	in instance methods, use OTHER only if it is locally
	declared.

	the global class method hash table.

	throughout.
