Yes, it's complicated in theory at least.

Obviously, it is a gray area, but there's a significant difference between quoting a sentence or three from the standard and reproducing/redistributing the standard. > I know that some POSIX documents were re-released under a free-ish > licence some time ago for inclusion into some manual pages, but I > don’t have a reference for that and don’t know the scope.

While I'm pretty sure they would allow this without problem, I'm wondering if it's worth the effort. Ideally, we'd have text written by someone in their own words. Reproducing the text of the standard has limited value, since people can in any case consult the standard directly. Alex, how about we just go much simpler, saying something like: [[ This type represents floating-point status flags; for further details see fenv(3). ]] Thanks, Michael -- Michael Kerrisk Linux man-pages maintainer; http://www.kernel.org/doc/man-pages/ Linux/UNIX System Programming Training: http://man7.org/training/
