Bug#1103067: Patch to fix

[Dima Kogan]

To fix this it's necessary to add the "long long int" flavor of
make_unsigned to Meta.h (such as done in the attached patch). I'll run
some more tests (primarily to make sure this doesn't break amd64) in the
next few days and do a Team upload, if nobody beats me to it.
