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