But it is not cleanly programmed.  It depends on the quite arbitrary
behavior of the GNU utilities to have the int types 32 bits, while
ANSI garantees only long to have that length.
I use the following clutch to optimize memory usage.

# define INTEGER_LENGTH (32 / 8)
# if sizeof(int) >= INTEGER_LENGTH
  typedef int Integer;
# else
  typedef long int Integer;
# endif

It's not too hard to implement this on the postprocessors.

BTW, I finished the libdriver/input.cc file.  Do you need it urgently,
or are there some more days left for polishing?
