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.
