AC_SUBST_DIR(VARNAME, [DIR])
1.1.1.1 (2001/07/26) Miscellaneous @ ac-archive-0.5.39
Mathias Hasselmann <mathias.hasselmann@gmx.de>
This macro substitutes (with AC_SUBST) VARNAME with the expansion of itself or the DIR variable if specified, taking care of fixing up ${prefix} and such.
Side effect: VARNAME is replaced with the expansion.
AC_SUBST_DIR bases on Alexandre Oliva's AC_DEFINE_DIR macro.
Examples:
AC_SUBST_DIR(DATADIR)
AC_DEFUN([AC_SUBST_DIR], [ ifelse($2, , $1, $1="[$]$2") $1=`( test "x$prefix" = xNONE && prefix="$ac_default_prefix" test "x$exec_prefix" = xNONE && exec_prefix="${prefix}" eval echo \""[$]$1"\" )` AC_SUBST($1) ])
