[Groff] problem with generating html version of manual

[Joerg van den Hoff]

attempting  to  generate the html version of the manual, but
with groff 1.19.3 I ran into the following problem: after

./configure
make
cd doc
make groff.html

I get
----------------------------CUT----------------------------------
makeinfo --enable-encoding -I. --html --no-split groff.texinfo \
&& /bin/sh ./fixinfo.sh groff.html
groff.texinfo:495: warning: @menu seen before first @node, creating `Top' node.
groff.texinfo:495: warning: perhaps your @top node should be wrapped in
@ifnottex rather than @ifinfo?.
groff.texinfo:518: Node `Top' previously defined at line 495.
makeinfo: Removing output file `/Users/vdh/Desktop/groff_cvs/doc/groff.html' due
to errors; use --force to preserve.
make: *** [groff.html] Error 1
----------------------------CUT----------------------------------

whereas

`make groff.pdf'

works just fine (apart from _lots_ of `warning: undefined flag: Lbracemacro'
warnings and a few "overfull \vbox"es.  am I missing something?
