Mechanical change to sink a #ifdef guard for a platform below the
include of int_lib.h.

The purpose of this change is to make the C code conform to the pedantic
rules of C99 -- an empty translation unit is not valid. It should have
absolutely no functional impact, and changes nothing about the built
libraries.
