Well, it changes the signedness of the computation on 32-bit, and in
combination with the fact that "len" is always smaller than 2^32, but
may exceed 2^31-1, the change avoids the dependency on the undefined
behavior of signed integer overflows in C on 32-bit as well. But I
admit that this might be a rather academic point...
Anyway, my motivation for the patch was the improved error reporting.
Is the drive-by type change a problem here?

Andreas
