Re: [PATCH] Fix PR c++/26884

This version looks fine -- but watch your line-wrapping; it looks like you're close to exceeding the 72-column width. If you are, make sure you wrap appropriately before check-in, e.g.:

  if (TREE_CODE ...
      && TREE_CODE (init) ...)

  error ("array ... "
         "brace-enclosed initializer");


Tested on mainline and 4.1 with no regressions on i686-pc-linux-gnu. Applied thus on mainline and 4.1.
