Thank you. Your patch has been applied in our development stream.

There are still uses of changequote() in aclocal.m4 which need to be dealt
with. If you fix them then it'll be easier for me. :-) One of them, for
example, relies on patsubst() being expanded so I'm not sure what'll happen if
that line is quoted.

Thanks for your patch.
