dnl diff comments with line numbers might be a pain to maintain.  When that

dnl For example, in AWK:
dnl
dnl   getline $!4*0;
dnl
dnl The grammar below (from GNU AWK 3.1.0) using canonical LR(1) or IELR(1)
dnl parses it as:
dnl
dnl   getline $!(4*0);
dnl
dnl That is, they shift '*' immediately and make it part of the getline
dnl argument.
dnl
dnl The grammar below using LALR(1) parses it as a syntax error.  So does
dnl GNU AWK 3.0.6, 3.1.0, and 3.1.1.  They reduce the full getline expression
dnl before shifting '*' even though '*' is not a valid lookahead.
dnl
dnl GNU AWK 3.1.2, 3.1.3, 3.1.4, and 3.1.5 parse it as:
dnl
dnl   (getline $!4)*0;
dnl
dnl That is, like the other versions of GNU AWK, they reduce the full getline
dnl expression before shifting '*'.  However, because of a different LHS on the
dnl getline rule, '*' actually is a valid lookahead.  Solaris /usr/xpg4/bin/awk
dnl and the Open Group awk specification seem to agree:
dnl
dnl   http://www.opengroup.org/pubs/online/7908799/xcu/awk.html
dnl
dnl /bin/nawk and /bin/awk on Solaris 10 report it as a syntax error, but they
dnl don't like even 'print $!4;'.
