2011-04-14  Nicola Pero  <nicola.pero@meta-innovation.com>

	* c-parser.c (c_parser_objc_class_declaration): Updated call to
	objc_declare_class.

In gcc/c-family/:
2011-04-14  Nicola Pero  <nicola.pero@meta-innovation.com>

	* stub-objc.c (objc_declare_class): Updated argument name.

In gcc/cp/:
2011-04-14  Nicola Pero  <nicola.pero@meta-innovation.com>

	* parser.c (cp_parser_objc_class_declaration): Updated for change
	in objc_declare_class().

In gcc/objc/:
2011-04-14  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_declare_class): Changed to take a single
	identifier as argument instead of a tree list.  This means callers
	don't have to build temporary tree lists to call this function.
	(synth_module_prologue): Updated calls to objc_declare_class.
