That is untrue by definition, since two's complement is strictly
a mechanism for representing negative values, which the unsigned
types do not do.

That said, parser states are more of an enumeration. They are identifiers.
We shouldn't be doing any math on them of this sort.
That may be true in theory, but not in practice. For example, the GLR
skeleton's yyLRgotoState has this line:
int yyr = yy

Thanks for the answer! (And thanks to Kaz too)
