Bug 12613

  A declaration of an array with an array index causes an ICE on 3.3/3.4.

  When C++ parser calls build_tree_list() (or tree_cons()) with
PURPOSE parameter, this function makes a TREE node which TREE_PURPOSE is
non-NULL. Then reshape_init()'s array initializer processing routine
passes its PURPOSE to size_binop(), which causes type mismatch and an ICE.

Environment:
(a) Debian GNU/Linux testing (GCC version 3.3.2 20030908 (Debian prerelease))
  and
(b) FreeBSD 5.1-CURRENT (GCC version 3.3.1)
  and
(c) FreeBSD 4.8 (GCC 3.4 cvs at 2003/10/07 (JST))

How-To-Repeat:
  To compile these files:

---- ice1.ii
int a[] = { [1] 1 };
---- ice2.ii
enum { FOO = 1, BAR = 2 };
int a[] = { FOO: 1, BAR: 2 };
---- ice3.ii
int a[] = { FOO: 1, BAR: 2 };
---- end

  ice1.ii is GCC's old-style C-extention code, and ice2.ii and ice3.ii
are both invalid code.
