Hi Sébastien,

AC_ARG_WITH([foo],
            [AC_HELP_STRING([--with-foo=whatever],
                            [Specifies something for foo @<:@default  
value here@:>@])],
            [], [with_foo=no])

case $with_foo in
   no) echo some default action
       ;;
  bar) echo do whatever you want
       ;;
    *) AC_MSG_ERROR([Invalid value for --with-foo: `$with_foo'])
       ;;
esac

Is that what you want?

Cheers,
