Yes, I was trying to tell you what I think the POSIX spec intends. :)
In any case, as I said before, this debate of what they meant could
last a
while. So, I suggested the short cut of just choosing what bison
should
do for --yacc based on a portable interpretation of the spec.
The problem is that we do not know what this interpretation ought to
be. If one does not want to break old code, then one can stick with
what has been in the past.
One example is the unofficial
compile C as C++ that existed for awhile, but that was abandoned
in view that
it was too difficult to maintain.
This is way off topic, but when was this abandoned? make
maintainer-check
would need to be updated.
The compile C as C++ option was never official, therefore no notice
was made, I gather. But it was a few years ago. The point is that the
$$ = $1 seems to fall into the same category: not explicitly
official, but used by some because it works.
