"Converting -1 to an unsigned type always sets all the bits"
 
In any normal twos complement architecture that's the case. But there
are a few oddballs out there where -1 is +1, except that the dedicated
sign bit is set.

There may be hardware where that is true, but a conforming
implementation of C targeting that hardware cannot use the hardware's
result. It must fix up the result produced by the hardware to match the
result required by the C standard.
