If you're talking about the is*() and to*() APIs from libc then that
doesn't seem to make any sense for a standards compatible program.
The definitions in all of the standards, an in the NetBSD manual
pages, all request that the parameters for these functions are to be
passed as (int).
Unfortunately even various NetBSD architectures, at least for some
releases, are inconsistent in how these interfaces are defined and
what warnings are given for various usages. I've had the best luck
getting the least warnings on a wide variety of platforms by always
casting to (int) too.
