Hi all,

I want to produce a help string like this:

    --with-foo[=DIR]            Use the foo package

(note the []s around the =DIR bit). When I use the option like this:

AC_ARG_WITH([foo],
            [AC_HELP_STRING([--with-foo[=DIR]],
                            [Use the foo package])],,)

It produces:

    --with-foo=DIR            Use the foo package

Is there a way to make it produce the []s that I want?

Have you been trying double-[[ and triple-[[[ pairings? That is
the normal way to pass literal "[" around and used widely
within m4/autoconf. It is needed for such simple things as
passing sed-char-ranges around (AC_X([sed -e `/[[0-9]].......)
