Please note about the #define unsigned before. This trick is a bit
ugly but already in use at many places to get an signed type by
__SIZE_TYPE__ macro. As prior version worked on signed integers, I
kept here this.
Maybe an idea would be to define as builtin macro also the
__SSIZE_TYPE__, but as this isn't present at the moment this kludge
works fine.
