OK.  Looking into the autoconf info pages, your argument is valid.
However, the following lines

  OPTS=`grep ':.*:.*:' groff.cpp \
        | sed -e 's/[",]//g'`
  OPTS_NO_ARG=`echo $OPTS \
               | sed -e 's/[a-zA-Z]://g'`
  OPTS_WITH_ARG=`echo $OPTS \
                 | sed "s/[$BAR:]//g"`

do exactly the same job...

If you insist on using perl, please do the following:

  (1) change the permissions of `read_groff_options.pl' to 644
  (2) in Makefile.sub, use $(srcdir)
  (3) don't call the script directly but use $(PERL)
  (4) fix the `make' dependencies: the output depends on `groff.cpp'
      also
