__USE_GNU is not supposed to be defined on any platform except on glibc platforms, and glibc platforms have the macros EAI_INPROGRESS ... EAI_IDN_ENCODE. You can define _GNU_SOURCE on any platform (and it will have no effect except on glibc systems), but you must not define __USE_GNU. The two underscores with which this identifier starts make it easy to remember. Bruno
