Hello,
I don't think anything changed with this bug, which still prevents
gprolog's inclusion in any stable release, and affects Ubuntu as well.
I believe just pulling the latest upstream source would fix it.
Alternatively, if downgrading to the stable gprolog-1.4.4 is an option,
the attached patch lets it compile with gcc 6. Tested on Debian 9.4.
Thanks in advance,
Cedric Ware.
