autoreconf failures on 0.18.2 and 0.18.3

On cloog 0.18.2 and 0.18.3, attempting to perform an autoreconf fails out with the following:

autoreconf: Entering directory `.'

autoreconf: configure.ac: not using Gettext

$ ls cloog-0.18.1/isl/interface/

all.h  extract_interface.cc  extract_interface.h  isl.py.top  Makefile.am  Makefile.in  python.cc  python.h

$ ls cloog-0.18.2/isl/interface/

all.h  isl.py.top

$ ls cloog-0.18.3/isl/interface/

all.h  isl.py.top

These files are present within the git repository as well.  Was there a reason that prompted the change?

Thanks,
