127, right? I know at least RISC processors tend to have instructions
for both a logical and algebraic right shift. In that context, it makes
sense for a systems programming language.
Surprise! c == -1.
Because 1 is an int, b gets promoted to int before the shift happens.
Then the result is 0x7FFF_FFFF which then gets converted to byte,
leaving 0xFF == -1.
