I installed this patch into gnulib to catch the problem there, too.

Check for 64-bit int errors in HP-UX 10.20 preprocessor.
Problem reported by H.Merijn Brand in
<http://lists.gnu.org/archive/html/bug-tar/2007-10/msg00018.html>.
* m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Check preprocessor too.
* m4/ulonglong.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
