I just successfully built innoextract 1.4-1 from the Debian source in a Sid chroot with GCC 5, and tested the resulting binary on an InnoSetup installer, with success again.
I do not have the basic knowledge to understand the given wiki.debian.org link, so I might be missing something obvious, but it seems to me that innoextract is actually compatible with GCC 5. innoextract is heavily used in one of my current projects, so tell me if I can do anything to help on this matter ;) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
