   Note that for the VAX, the V6-->V7 change was effectively a no-op.   
      
   There were no kernel changes to the VAX code that would have required   
   a major version bump.   
      
   Typically, at a major version change, the kernel is rototilled in such   
   a way as to require changes to LIB.REQ, LIB.MLB, and SYS$LIB_C.TLB.  Things   
   like   
   kernel data structure changes (reordering fields for better alignment, etc).   
      
   That didn't happen to any VAX kernel structures.
