Subject: c-parse.in (array_declarator): New.

	* c-parse.in (array_declarator): New.  Handle C99 constructs.
	Don't restrict [*] declarators to C only.
	(after_type_declarator, parm_declarator_starttypename,
	parm_declarator_nostarttypename, notype_declarator,
	direct_absdcl1): Use it.
	* c-decl.c (build_array_declarator, set_array_declarator_type):
	New functions.  Warn that [*] isn't properly implemented; pedwarn
	for [*] outside C99 mode if pedantic rather than giving a hard
	error.
	(grokdeclarator): Handle static and type qualifiers in parameter
	array declarators.
	* c-tree.h (build_array_declarator, set_array_declarator_type):
	Declare.
	* extend.texi (Attribute Syntax): Document attributes in parameter
	array declarators.

testsuite:
	* gcc.dg/c90-arraydecl-1.c, gcc.dg/c99-arraydecl-1.c: New tests.
