[PATCH] fortran/arith.c -- Fix the range of integers in overflow checks

[Jack Howarth]

Steve,
   Do you mean whether we have a signed short? I believe so since I see
both...

typedef        short                   __int16_t;
typedef        unsigned short          __uint16_t;

...in /usr/include/ppc/_types.h on my MacOS X box.
                    Jack
