     1 dnl We are not running in a real autoconf environment. So we're using real m4

     2 dnl here, not the crazier environment that autoconf provides.

     4 dnl Autoconf expects [] for quotes; give it to them

     5 changequote([, ])

     7 dnl AC_DEFUN is provided to use instead of define in autoconf. Provide it too.

     8 define([AC_DEFUN], [define($1, [$2])])

    10 dnl AC_ARG_ENABLE(FEATURE, HELP-STRING, IF-TRUE[, IF-FALSE])

    11 dnl We have to ignore the help string due to how help works in autoconf...

    12 AC_DEFUN([AC_ARG_ENABLE],

    13 [#] Check whether --enable-[$1] or --disable-[$1] was given.

    14 [if test "[${enable_]patsubst([$1], -, _)+set}" = set; then

    15   enableval="[$enable_]patsubst([$1], -, _)"

    16   $3

    17 ifelse([$4], , , [else

    18   $4

    19 ])dnl

    20 fi

    21 ])

    23 dnl AC_MSG_ERROR(error-description)

    24 AC_DEFUN([AC_MSG_ERROR], [{ echo "configure: error: $1" 1>&2; exit 1; }])

    26 AC_DEFUN([AC_MSG_WARN],  [ echo "configure: warning: $1" 1>&2 ])

    28 dnl Add the variable to the list of substitution variables

    29 AC_DEFUN([AC_SUBST],

    30 [

    31 _subconfigure_ac_subst_args="$_subconfigure_ac_subst_args $1"

    34 dnl Override for AC_DEFINE.
