I guess you were relying on an implicit #include via some other
explicitly-included header, and maybe this implicit inclusion is
different for different ARCHes, so that this only fails to compile under
certain configurations.

Yes, that is the right thing. Standard practice is to explicitly include
any required headers, so that changes in unrelated headers don't break
things.
