dnovillo/cxx-conversion git branch failed to bootstrap on
Fedora 17 x86-64 when configured with

--enable-languages=c,c++,fortran,java,lto,objc,obj-c++,go

I got

/export/gnu/import/git/gcc-x32/gcc/objc/objc-act.c: In function
\u2018tree_node* objc_build_constructor(tree,
vec_t<constructor_elt_d>*)\u2019:
/export/gnu/import/git/gcc-x32/gcc/objc/objc-act.c:3212:44: error:
base operand of \u2018->\u2019 has non-pointer type
\u2018constructor_elt_d\u2019
   if (!VEC_index (constructor_elt, elts, 0)->index)
