No it's not:
--11:32:26-- 
ftp://ftp.cs.colorado.edu:21/pub/mktemp/mktemp-1.3.1.tar.gz
           => `mktemp-1.3.1.tar.gz'
Connecting to ftp.cs.colorado.edu:21...

Yup.  It means that

   AC_DEFINE(HAVE_PROGNAME)

is used, but that none of the uses specify the comment to use.
Autoheader wants to create config.h.in header that look like

  /* blah */
  #define FOO <optional value>

For the 'blah' part, it has to rely on the user to tell it what to use. 
In the olden days, acconfig.h was used for that purpose, but now
autoheader expects AC_DEFINE to do it:

  AC_DEFINE(HAVE_PROGNAME, 1,
            [Define if your system has the progname() function.])

Or something like that.
So often these messages can be resolved quite easily by simply looking
for AC_DEFINE's that lack a third argument, and add it (often a legacy
acconfig.h will be present, in which case you can just lift the comment
from there), optionally adding a value as well ('1' is usully OK).

Hope that helps.
