 401 dnl The grammar below (from GNU AWK 3.1.0) using canonical LR(1) or IELR(1)
 402 dnl parses it as:
 403 dnl
 404 dnl   getline $!(4*0);
 405 dnl
 406 dnl That is, they shift '*' immediately and make it part of the getline

 409 dnl The grammar below using LALR(1) parses it as a syntax error.  So does
 410 dnl GNU AWK 3.0.6, 3.1.0, and 3.1.1.  They reduce the full getline expression
 411 dnl before shifting '*' even though '*' is not a valid lookahead.
 412 dnl
 413 dnl GNU AWK 3.1.2, 3.1.3, 3.1.4, and 3.1.5 parse it as:
 414 dnl

 416 dnl
 417 dnl That is, like the other versions of GNU AWK, they reduce the full getline
 418 dnl expression before shifting '*'.  However, because of a different LHS on the
 419 dnl getline rule, '*' actually is a valid lookahead.  Solaris /usr/xpg4/bin/awk

 423 dnl
 424 dnl /bin/nawk and /bin/awk on Solaris 10 report it as a syntax error, but they
 425 dnl don't like even 'print $!4;'.
