Quick work.  Thanks!

However, not yet fixed.

After spending an hour or two with the automake and autoconf infopages, I 
THINK what's happening is that in this:

if test "x$want_gnome_doc_help" = "xyes" ; then

... the first and last lines are final-configure-file shell code that's 
not actually run until configure itself is executed; until then they're 
simply treated as string-literals and left alone.  Meanwhile, the middle 
line consists of the AC_CONFIG_FILES macro that must be expanded BEFORE 
the final configure file is executed as it's used to CREATE that final 
configure file, with help/Makefile fed to that macro as a parameter...

To prove my suspicions I changed the "xyes" above to "xno", with no 
change in result -- it still pulled in (and broke with) help/Makefile 
either way, as it would if it were treating the first and last lines as 
literal pass-thru text, while trying to handle the middle one.

HOWEVER!  I DID trace the problem one file further down.

In help/, if I #-out the first line to this:

#include $(top_srcdir)/gnome-doc-utils.make

... it works.  Further, if * take out the $(top_srcdir)/ bit, the 
automake.out error then refers to help/gnome-doc-utils.make instead of
just gnome-doc-utils.make, and if I change it to xgnome-doc-utils.make, 
it's that in the error.

So we're getting closer.  In addition to making the error disappear by 
removing or commenting the line, I can change the error by changing the 
line, which is more than I was getting before!

Also, simply touching the gnome-doc-utils.make file in question, 
presumably only if help is disabled, so the file exists but is empty, 
works.  But of course I don't know how to do that before that include...

Too tired to make much further sense of anything at this point.  
Hopefully the post makes sense.  Maybe after some sleep...
