Xpetra appears to require GlobalOrdinal=int even when Tpetra_INST_INT_INT=OFF

Xpetra appears to attempt to instantiate Tpetra::Map<int, int, ...>, or at least to use its declarations, even when Tpetra_INST_INT_INT=OFF. For example, when I put a static_assert in Tpetra::Map that requires GlobalOrdinal == long long, I am able to build all of Tpetra, but get the following Xpetra build errors:
