// systems, and the semantics of operations are a bit different. Will take
// some real work to get this going.

// to implement it aren't exported by default. You need to use smit to enable
// them. So, leave AIO disabled unless the user explicitly enables it.

// feature-test macros, so set up _ACE_DISABLE_AIO_CALLS_ if the user didn't
// set it. Then check for it after including config-aix-4.x.h and remove
// ACE_HAS_AIO_CALLS if so.
