yes, it's the latest stable version.
But there is a development version updated every 6 hours available at
  http://www.engelschall.com/sw/wml/distrib/

I already worked on this problem, see below.

I took a look in the ChangeLog file and i think there was no change
between 1.6.4 and 1.6.8 for the 4th pass.

In this case, a patch is fine.  I like patches generated by diff -u :-)

Here is what i did:
  m4_define(`m4_noquotes', `m4_changequote()')m4_dnl
  m4_define(`m4_quotes',   `m4_changequote`'')m4_dnl

The m4_dnl are removed from inside macros, i think it's the user's
choice to add m4_dnl or not.

These definitions moved from wml.src to bootgm4.src
You could have a look at
