[patch] Fix PR c++/27821

["Lee Millward" <lee dot millward at gmail dot com>]

Hi,

The C++ front-end currently ICE's with an assertion failure in
build_ptrmem_type with the following invalid testcase:

struct A
{
   template<void (A::*)()> struct B {};
   void ::foo();
   B<&A::foo> b;
};

The proposed patch fixes the ICE by returning error_mark_node from
inside grokdeclarator when an invalid use of "::" is detected.

Bootstrapped and regresstion tested on i686-pc-linux-gnu with no new
failures. Ok for mainline?

Cheers,
Lee.
