Do we promise that userland will compile with -std=c89? I hope not. Anonymous unions may be a c11 feature, but they're also available with -std=gnu99, which I think is how we compile userland. I think -std=gnu99 is how we should also compile the kernel, and I think Bruce has been trying to say that for several years (but I'm not sure, because the emails that seem to say so are always so full of semi-related extraneous material that it's hard to be sure what they're saying). -- Ian _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
