It's because libc still supports 80386 which doesn't have bswap (introduced on the 486 IIRC). The kernel only supports 486+ unless you explicitly build an 80386 kernel, which won't use bswap for htonl(). -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
