[3.0.4] Request: please revive the deleted arrays yyrhs and yyprhs |

Hello,
Our system is utilizing GNU Bison in Cygwin in yacc mode (by -y) in busuness.
Thank you for your maintaining Bison and correcting original miss comments,
arranging obsolete compile options, etc.
In bison 2.x.x, the arrays
yyrhs and yyprhs
in the file
y.tab.c
is very useful, so our program depends on them in real business.
The other day, we updated Cygwn environment and found that
the array variables yyrhs and yyprhs disappeared in bison 3.0.2 and 3.0.4,
and that bison 2.x.x is no longer existing in the Cygwin ftp directory list.
(An 2.7.1 binary for Cygwin was found at a certain ftp site, but it did not
work in the current Cygin environment. )
(The Bison command line option -t (or --debug) did not bring effect as this
point. )
Though the two variables might have be written only for debugging by the
original developer, but we need them every day in the form of machine-reading.
So, we are now very puzzled whether we should develop and maintain a program
code to make the two variable values correctly from the rest information in the
file. But, it could be very difficult, because of the complex related functions
and the troublesome (about 251) bias of yytype, we found after some trial.
If you could revive the variable in the next version Bison soon and inform us
via this mailing-list, we would be very happy.
Thank you in advance.
