Hi all, A few years ago I fixed most of the cases where we used 1 << 31 in FreeBSD. This expression is illegal in C. Since then the issue has arisen again. https://reviews.freebsd.org/D13858 fixed most of the non-contrib cases. I'd also like to see if we could find some more general solution, be it a compiler warning, bit set macro, or otherwise. -- Eitan Adler
