Thanks for doing that.

Rather than modify the code, how about if we change coreutils to not
use 64-bit integer types if they have that bug?  After all, if there's
one bug there are likely to be others.

Does the HP-UX 10.20 compiler crash with the following program?  If
not, is there some other simple program that it does crash on?

   long long ll = 1LL;
   int i = 63;

   main (void)
     long long llmax = (long long) -1;

     switch (llmax)
       case -2:
         return 1;
       case -1:
         return 2;
         return ll << i | ll >> i | llmax / ll | llmax % ll;

Perhaps all we need to do is substitute our on bool type for the
compiler's broken one.  How was the 'bool' type defined on your
platform?  Was lib/stdbool.h created, or the compiler's stdbool.h
used?  What is the value of HAVE_STDBOOL_H in config.h?  HAVE__BOOL?
Are these values correct?
