Supporting this, with the new patch would be to add something like this to
config.status:
ac_file_inputs=`IFS=:
for f in $ac_file_in; do
case "$f" in
-) echo $tmp/stdin ;;
+ !*) echo $f | cut -c2- ;;
*) echo $ac_given_srcdir/$f ;;
esac
done`
Use sed if cut isn't portable. Anyways, I don't like using ! to tag the
builddir files because ! and bash (interactive at least) is a whole other
chapter...
What could be done is to implicit prefer builddir-sources to srcdir-sources,
but because there would be some "magic" involved (test -f) the behaviour
could be perceived to be inconsistent, so an explicit tag is probably the
best idea...
