/* Find HOST_WIDEST_INT and set its bit size, type and print macros.
It will be the largest integer mode supported by the host which may
(or may not) be larger than HOST_WIDE_INT. This must appear after
<limits.h> since we only use `long long' if its bigger than a
`long' and also if it is supported by macros in limits.h. For old
hosts which don't have a limits.h (and thus won't include it in
stage2 cause we don't rerun configure) we assume gcc supports long
long.) Note, you won't get these defined if you don't include
{ht}config.h before this file to set the HOST_BITS_PER_* macros. */
