# 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.])
