-// AtomicWord is a synonym for intptr_t, and Atomic32 is a synonym for int32,
-// which in turn means int. On some LP32 platforms, intptr_t is an int, but
-// on others, it's a long. When AtomicWord and Atomic32 are based on different
-// fundamental types, their pointers are incompatible.
-//
-// This file defines function overloads to allow both AtomicWord and Atomic32
-// data to be used with this interface.
-//
-// On LP64 platforms, AtomicWord and Atomic64 are both always long,
-// so this problem doesn't occur.
