"os_aix" implies that is OS-specific code for AIX. Unless you are building the binary for AIX, that 
code would not get compiled.

The correct way is to either get the AIX machine to test this change, or kindly ask AIX port 
maintainers to test it for you.

But chances are, you don't need that if you are just prototyping the change, which must be fine for 
a single target platform you have (I assume something like Linux x86_64).
