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.
