It appears that it at least caused by buggy memcmp() on SunOS4. In
bit_cmp():
cmp = memcmp(VARBITS(arg1), VARBITS(arg2), Min(bytelen1,bytelen2));
would return unexpected result if the sign bit of the first byte is
on. For example, B'11011000000' is smaller than B'00000000000'.
The only solution would be having our own memcmp on SunOS4.
