cherry-picked to the 3-4 branch.  It fixes

I see how ulimit_cast is the wrong choice there, but:

If I understand well, static_cast<unsigned int>(a) where a is a signed
int returns a+2^n where n is the length of int in bits.

For example, for 32 bit ints, static_cast<unsigned int>(-1) is
2^32-1.

Why is that the best solution, rather than 0, which as far as I
understand, limit_cast<unsigned int>(a) would use?
