OK, I've found the culprit: the variable is created in
gfc_trans_vla_one_sizepos(). However, it makes no sense to issue warnings about
anonymous variables, since these are emitted by the front-end for internal
business, and don't refer to user code. Thus, we can simply get rid of it as a
whole, with:
Index: trans.c
