63 Samba needs type definitions for int16, int32, uint16 and uint32.
65 Normally these are signed and unsigned 16 and 32 bit integers, but
66 they actually only need to be at least 16 and 32 bits
67 respectively. Thus if your word size is 8 bytes just defining them
68 as signed and unsigned int will work.
