This has already been discussed to death.  Flexnames, no.  Longer limits,
where practical, yes.

I don't know about the first part, but <FLAME ON> the second part is
probably true already <FLAME OFF>.

The draft says, I believe, that member names are local to the structure
they are declared in.  So the above is legal.  Note that it's legal in
V7 C too, but for different and much sleazier reasons.
