2 *  ntp_types.h - defines how int32 and u_int32 are treated.
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

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