I believe Eric's comment
http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00179.html points at the correct
fix, but it's a bit messy.  You need to recursively descend both "decl" and
"init" in code like c-decl.c:finish_decl, updating "decl" component sizes for
any variable length arrays you find, rather than handling just a top level
variable length array as we do currently.  Then repeat the exercise for other
language versions of finish_decl..
