To do so, Configure must be run with -Dusethreads.

In the following, larger digits indicate more significance. A big-endian
machine like a Pyramid or a Motorola 680?0 chip will come out to 4321. A
little-endian machine like a Vax or an Intel 80?86 chip would be 1234. Other
the test program works the default is probably right.
