Thanks for this change. After it the anonymous unions in xinpcb, unpxb are no longer needed. Do you agree? I added them to make sizes on 32-bit and 64-bit ABIs to be identical. I prefer your new code, but didn't the unions work? Anyway, now they can be removed. -- Gleb Smirnoff _______________________________________________ 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"
