The problem is that the current draft has addressed the issue.  It says 
32 bit numbers and no roll over.  If you wish to leave it open as 977 
did, you need to remove the current text on the matter.  In either case 
you still have to make a change to the current draft.  Either leave it 
open, or specify 64 bit numbers.  I think it's just as easy to change to 
64 bit numbers as it is to remove the current 32 bit limit. 

The very old unix clients are not normally used on modern binary 
servers.  Any 64 bit change would not effect them for several years and 
by that time 32 bit computers will not be in use.
