--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think there is no good way apart from treating single-element structs equal
to its single element in LTO with regarding to TYPE_CANONICAL. At least not if
you want to inter-operate with both int i; and struct { int i; }. Otherwise
I'd lean towards not using a struct in Fortran for single-element commons.
That should be an implementation detail anyways.

But then simply name the symbol of the variable without a struct in that way,
no?
