I take that back.  It works for me if I use lowercase "print", which is an
awk command.  The uppercase "PRINT" is interpreted as an (empty) awk
variable, and awk interprets a constant expression in statement context
just like C does -- i.e., it ignores it.  This is not Cygwin-specific;
you'll get the same results on Linux.
