Subject: Bash heredoc on FD 3
Content-Type: text/plain; charset=utf8; format=flowed
User-Agent: Tryst/2.8.0 (cup.github.io/umber/awk/tryst)

Using this file:

    $ cat hello.sh
    awk -f /dev/fd/3 3<<eof
    BEGIN {
      print "hello world"
    }
    eof

it runs as expected with Dash:

    $ dash hello.sh
    hello world

However it fails with Bash:

    $ bash hello.sh
    awk: fatal: can't open source file `/dev/fd/3' for reading (No such file or
    directory)

I tried also with Debian and both Dash and Bash work as expected. What is
causing Cygwin Bash to fail here?
