c-common.h: Update comments about ObjC/ObjC++ entry points.

[gcc/ChangeLog]
2004-08-28  Ziemowit Laski  <zlaski@apple.com>

	* c-common.h: Update comments about ObjC/ObjC++ entry points.
	(objc_is_reserved_word): New prototype.
	(get_current_scope, objc_mark_locals_volatile): Move prototypes to
	separate section; these are call-backs.
	* c-lex.c (c_lex_with_flags): Call objc_is_reserved_word() to detect
	ObjC/ObjC++ "@" keywords.
	* c-tree.h (get_current_scope, objc_mark_locals_volatile): Remove
	prototypes; they already live in c-common.h.
	* stub-objc.c: Update copyright notice.
	(objc_is_reserved_word): New stub.

2004-08-28  Ziemowit Laski  <zlaski@apple.com>

	* Make-lang.in (CXX_OBJS): Split up into CXX_OBJS and
	CXX_AND_OBJCXX_OBJS.
	(CXX_C_OBJS): Include in CXX_AND_OBJCXX_OBJS instead of listing
	separately on the link line.
