Re: CygWin-1.7.3-1 fails to provide pipe. (merge back into trunk please)

["will.dutt" <will dot dutt at gmail dot com>]

my mistake, so i've done some more testing and found another bug to do with
fifo, i thought this patch had corrected. 

i get this error from tee.
tee: read error: Communication error on send

at

exec 3>&1 4>&2
tee $OUTPUT_LOG < $OUTPUT_PIPE >&3 &

regards william d.

p.s. Here is my test script

#!/bin/bash

OUTPUT_LOG=output.log
OUTPUT_PIPE=output.pipe

if [ ! -e $OUTPUT_PIPE ]; then
    mkfifo $OUTPUT_PIPE
fi

if [ -e $OUTPUT_LOG ]; then
    rm $OUTPUT_LOG
fi

exec 3>&1 4>&2
tee $OUTPUT_LOG < $OUTPUT_PIPE >&3 &
tpid=$!
exec > $OUTPUT_PIPE 2>&1

echo "This is on standard out"
echo "This is on standard err" >&2

exec 1>&3 3>&- 2>&4 4>&-
wait $tpid

rm $OUTPUT_PIPE
