There are 3 questions: 1) Do you think it is technically possible to support the iOS variants in Gnulib? 2) Do you think it makes sense for the GNU project to support the iOS variants? 3) Do you think we need to document that Gnulib doesn't support the iOS variants? My take on these questions would be: 1) For an OS that does not have files with file names, it's pointless to even think about open(), exec(), and so on. 2) Anyone buying and using these devices has surrendered their entire freedom and privacy to Apple. There is no point for GNU to help make these devices more widely spread by porting software to it. 3) I would think that the communities of POSIX / C users and iOS / Swift users are disjoint. Hence no need to document. Your take? Bruno
