Yep, that would help :)
Here is a small test case:
------------------------------------------------------------
#! /bin/sh
F77=/tmp/fake77
cat >$F77 <<\EOF77
#! /bin/sh
echo "Stdout"
echo "Stderr" >&2
EOF77
chmod +x $F77
exec 5>./config.log
ac_link='$F77 >&5'
# ====================
# Save the "compiler output file descriptor" to FD 8.
exec 8>&5
# Temporarily redirect compiler output to stdout, since this is what
# we want to capture in AC_LINK_OUTPUT.
exec 5>&1
ac_link_output=`eval $ac_link 2>&1 | grep -v 'Driving:'`
# Restore the "compiler output file descriptor".
exec 5>&8
# ====================
echo "$ac_link_output" | sed 's/^/| /'
------------------------------------------------------------
When run, this script says:
/tmp % ./f77test nostromo 11:15
Stdout
| Stderr
while it should be
| Stdout
| Stderr
IIUC.
You can only change what is in between the `# ===================='.
