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.
