Subject: re PR c/4787 (Different anonymous variables declared but only one
 allocated when the initialization is the same)

	* c-common.def (COMPOUND_LITERAL_EXPR): New.
	* c-common.c (c_expand_expr): Handle COMPOUND_LITERAL_EXPR.
	(c_staticp): New function.
	* c-common.h (COMPOUND_LITERAL_EXPR_DECL): New.
	(c_staticp): Declare.
	* c-typeck.c (default_function_array_conversion, build_unary_op):
	Don't handle CONSTRUCTOR specially.
	(lvalue_p, mark_addressable): Handle COMPOUND_LITERAL_EXPR.
	* c-decl.c (build_compound_literal): New function.
	* c-tree.h (build_compound_literal): Declare.
	* c-parse.in (primary): Use build_compound_literal.
	* c-lang.c (LANG_HOOKS_STATICP): Define.
	* objc/objc-lang.c (LANG_HOOKS_STATICP): Likewise.
	* doc/c-tree.texi: Document COMPOUND_LITERAL_EXPR.
	* doc/extend.texi: Update documentation of compound literals.
	Fixes PR c/4787.

testsuite:
	* gcc.c-torture/execute/20000722-1.x,
	gcc.c-torture/execute/20010123-1.x: Remove.
	* gcc.c-torture/compile/init-3.c: Don't use a compound literal.
