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

-dnl In Autoconf 2.60, ${datadir} refers to ${datarootdir}, which in turn
-dnl refers to ${prefix}. Thus we have to use `eval' twice.
