# 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.])
