* 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.
