Why didn't you say so right away?

Yes, because the file is listed twice, just a few lines away.  Just
remove the line completely, so that the file is listed only once.


In case you're interested in the reason behind the failure with dnl:
The AC_OUTPUT macro makes m4 look at its arguments in order.  And you
quote the argument list once.  Like so:
  AC_OUTPUT([file1
  file2
  file3
  ...
  ])

If you wanted to correctly comment out a line here, so that m4 would not
see the 'dnl' in the list at all, you would have to write something like
this:
  AC_OUTPUT([file1
  file2
  ]dnl file3
  [file4
  ...
  ])

Hope that helps.

Cheers,
Ralf
