Hi!
Using unsigned long long int for fmt_size_t and "ll" for GCC_PRISZ
as broke the gengtype on i686-linux before the libiberty fix is certainly
unexpected. size_t is there unsigned int, so expected fmt_size_t is
unsigned int (or some other 32-bit type).
The problem was that I was comparing SIZE_MAX against signed maxima,
but SIZE_MAX is unsigned maximum.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok
for trunk?

* hwint.h (GCC_PRISZ, fmt_size_t): Fix preprocessor conditions,
instead of comparing SIZE_MAX against INT_MAX and LONG_MAX compare
it against UINT_MAX and ULONG_MAX.
