 * Further investigation shows: In the different regions the highest bit

 * This is also the algorithm used for RtlUniform of wine (see dlls/ntdll/rtl.c).
 *
 * Now comes the funny part:
 * It took me one weekend, to find the complicated algorithm and one day more,
 * to find the simplified algorithm. Several weeks later I found out: The value
 * MAXLONG (=0x7fffffff) is never returned, neither with the native function
 * nor with the simplified algorithm. In reality the native function and our
 * function return a random number distributed over [0..MAXLONG-1]. Note
 * that this is different from what native documentation states [0..MAXLONG].
 * Expressed with D.H. Lehmer's 1948 algorithm it looks like:
 *
 * seed = (seed * const_1 + const_2) % MAXLONG;
 *
 * Further investigations show that the real algorithm is:
 *
 * seed = (seed * 0x7fffffed + 0x7fffffc3) % MAXLONG;
 *
 * This is checked with the test below:
