3 *  For 64 bit systems like the DEC Alpha, they have to be defined
4 *  as int and u_int.
5 *  For 32 bit systems, define them as long and u_long

15 * On NetBSD for MAC the macro "mac" is defined as 1
16 * this is fun for us as a packet structure contains an
17 * optional "mac" member - severe confusion results 8-)
18 * As we hopefully do not have to rely on that macro we
