Now that savannah is back up after hardware failure, and since Matthew confirmed off-list that this works, I'm checking in this. 2007-03-15 Eric Blake <[email protected]> Avoid Tandem/NSK's broken long long (without a symmetric unsigned long long, it confuses gnulib). * configure.ac (AC_TYPE_LONG_LONG_INT): Declare long long broken if unsigned long long doesn't work. * THANKS: Update. Reported by Matthew Woehlke. - -- Don't work too hard, make some time for fun as well!
