The OpenACC spec does not provide exact clarification on what "integer
expression" is - except in one spot in the spec:
```
5348 Async-argument – an async-argument is a nonnegative scalar integer
expression (int for C or C++, integer for Fortran)
```
It seems the intent is that they are 32-bit integers.
