Could someone given some details on these errors?  I have frequently
used pre-1.50 to bootstrap GCC, with success.  Unfortunately, due to
some stupid policy here, I have stopped downloading GCC and checking
it with the current Bisons.  Nevertheless, I can't imagine what
incompatibility can have been introduced in the meanwhile.

Also, I'm not sure how

| - CVS and CVS+patch, both bison-1.35: no regressions.
| - bison-1.35 and bison-1.50, both CVS+patch:

should be read: it seems to say that there are no regressions with the
patch and 1.35 (line 1), and there are regressions with the patch and
1.35 (line 2).
