Thanks a lot for pointing that out. I just wanted to point out to the fact that the MACRO that need to be defined (GNU_SOURCE) isn't mentioned in the info pages of libc. Or at least in the getline and getdelim section. I've been using getline for a while and always had the warning about the implicit declaration but thought it's kind of bug since I always include the mentioned header files. Do you think I should send this to the current maintainers of the info pages of libc ?
