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'
