I have gotten so tired on all newbies that write me personal mail without
cc-ing Help-Bison so that I nowadays use the list address as return
address. :-)

Always cc the GNU mailing list, unless you are positively sure it should
not be.

Bison should generate a Yacc compatible parser file according to what is
described in the POSIX standards. Thus, if those variable names above
appear in the POSIX standard, it is a bug in Bison, but otherwise your Yacc
version generates variables that are not in the POSIX standard, in which
the problem is that you are using variables that Bison will never support.
I do not know those things.

Bison bugs should be reported to Bug-Bison <address@hidden>. Make first
sure those variable names are not present in the header that Bison produces.
