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

* This leads to a simplified algorithm:
*
* seed = seed * 0xffffffed + 0x7fffffc3;

* seed = (seed + 2) & MAXLONG;

*
* 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:
