You're right 3.1.6 on Linux executes the script correctly,
while 3.1.6 on Cygwin terminates with an error message.
3.1.5 on both platforms works correctly.

One more hint: When implementing simple HTTP services
these days with gawk, I avoid the while loop that
swallows the incoming HTTP header and close the
connection immediately after having replied to the client.
This is necessary because most browsers (IE, lynx, w3m)
will cause the gawk server to hang after the first connection.
Only Mozilla-descendents like the Firefox and SeaMonkey
browsers behave nicely and will not cause the gawk server to hang.

Maybe I should have updated the doc earlier so that users
wouldnt run into this. But remember: This is _not_ the
cause of the problem that was reported by the OP. This is
just a hint.
