Volatile is not the solution, it is completely orthogonal. The correct
way would be to use unsigned integers, for which wrapping is defined,
then convert those back and forth when presenting the results to the
user.

After the clang 3.6.1 import, /bin/expr behaves differently.
With clang 3.5.0:

OK, converting expr.y to use unsigned integers would require a bit of work.
Can you commit your patch to the Makefile? It fixes the problem for now.
