Follow-up Comment #1:

This is already done; it was just hiding behind an m4 macro name that did not

AC_DEFUN([GROFF_HTML_PROGRAMS],
  [make_htmldoc=
   make_install_htmldoc=
   make_uninstall_htmldoc=
   make_htmlexamples=
   make_install_htmlexamples=
   make_uninstall_htmlexamples=
   AC_REQUIRE([GROFF_GHOSTSCRIPT_PATH])

   missing=
   AC_FOREACH([groff_prog],
     [pnmcut pnmcrop pnmtopng psselect pnmtops],
     [AC_CHECK_PROG(groff_prog, groff_prog, [found], [missing])
      if test $[]groff_prog = missing; then
        missing="$missing 'groff_prog'"
      fi;])
[...]


Closing as invalid.
