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