-# SYNOPSIS
-#
-#   AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
-#
-# DESCRIPTION
-#
-#   This macro sets VARNAME to the expansion of the DIR variable, taking
-#   care of fixing up ${prefix} and such.
-#
-#   VARNAME is then offered as both an output variable and a C preprocessor
-#   symbol.
-#
-#   Example:
-#
-#      AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])
