Hi Ben,

I glanced over the Debian-specific patches against Autoconf,
http://ftp.debian.org/debian/pool/main/a/autoconf/autoconf_2.59.cvs.2006.05.13-1.diff.gz
Some comments: (should I make this a wishlist bug in Debian BTS?)

- The variable quoting parts have been picked up by Paul in current CVS.

- This one isn't necessary any more, you can simply drop it:

- Was this one fixing a bug, or just for nicer config.log output?

- Then, there is an atomic replacement patch for autom4te.  Are you
  going to submit it to GNU Autoconf?

- There is a change to AC_PATH_X, apparently extending functionality.
  Is that relevant to Autoconf-2.60?

- Last but not least, you can simply drop the following patch, as
  the right hand side of assignments does not undergo word splitting.
