+dnl
+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;'.
