    10  # When I run the following AWK file...
    11  # 
    12  BEGIN {
    13      $0 = "00E0";
    14      print $0 ", " ($0 && 1) ", " ($0 != "");
    15      $1 = "00E0";

    19  # With the SimTel version of GAWK 3.1.1 for Windows (downloadable from 
    20  # ftp://ftp.cdrom.com/pub/simtelnet/gnu/djgpp/v2gnu/), I get the following 
    21  # output...
    22  # 
    23  # 00E0, 0, 1
    24  # 00E0, 1, 1
    25  # 
    26  # With the Cygwin version of GAWK 3.1.1 for Windows, I get...
    27  # 
    28  # 00E0, 1, 1
    29  # 00E0, 1, 1
    30  # 
    31  # As far as I know, if "$0" isn't blank, the value of "($0 && 1)" should be 
    32  # "1" (true). I get the same problem if I substitute "00E0" with "00E1" to 
    33  # "00E9". Other strings don't have have this problem (for example, "00EA"). 
    34  # The problem occurs whether I use file input or whether I manually assign 
    35  # "$0" (as above).
    36  # 
    37  # The problem is also discussed in a comp.lang.awk posting ("Bug in GAWK 
    38  # 3.1.1?", Dec. 27, 2002).
