utils.c (maybe_unconstrained_array): In the reference to unconstrained array case, deal with each branch of a COND_EXPR.
* gcc-interface/utils.c (maybe_unconstrained_array): In the reference
to unconstrained array case, deal with each branch of a COND_EXPR.
* gcc-interface/utils2.c (build_allocator): Deal with each branch of
a COND_EXPR in the initializer, if present.
