Looking more at cloog-ppl/configure I find stuff like:

fi;
Wich is obviously broken since all the tests are setting the same variable $withval and so --with-ppl just doesn't work. I looked at cloog-ppl-0.15 configure and it was ok.
The variable withval is only for use in the third argument (ACTION-IF-GIVEN) of AC_ARG_WITH. In all other places the variable with_PACKAGE should be used.
When I search for with_ppl in configure I get in order:
... # Check whether --with-ppl or --without-ppl was given. if test "${with_ppl+set}" = set; then withval="$with_ppl"
fi; ... echo "$as_me:$LINENO: checking for Parma Polyhedral Library (PPL)" >&5 echo $ECHO_N "checking for Parma Polyhedral Library (PPL)... $ECHO_C" >&6 if test "x$with_ppl" != "x" -a "x$with_ppl" != "xno"; then
if test "x$with_polylib_prefix" != "x" -o "x$with_polylib_exec_prefix" != "x" -o "x$with_polylib_builddir" != "x"; then { { echo "$as_me:$LINENO: error: --with-polylib and --with-ppl are mutually exclusive" >&5 echo "$as_me: error: --with-polylib and --with-ppl are mutually exclusive" >&2;} { (exit 1); exit 1; }; } fi
if test "x$with_ppl" != "xyes" ; then ...
So 0.15.3 configure does not set $with_ppl variable at all.
