Do we need to define _XOPEN_SOURCE at all? In the headers on OS X I found this comment: Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the available APIs to exactly the set of APIs defined by the corresponding standard, based on the value defined. I guess (at least) other BSD based systems handle this macro similarly (I'm too lazy to fire up a VM to check).
