 CS> 	The utsname structure defined in the sys/utsname.h has a maximum of
 CS> 	32 characters on all fields, including the 'nodename' - the network
 CS> 	name of the machine. This could reasonably be expected by a
 CS> 	programmer using the uname() call to be MAXHOSTNAMELEN in length.

 5.* fixes this using variable sized utsname. I think 4.* would not
 be fixed because their life is closed to finish.
