2 - switch to a multiplicative hash (developed with Steinar Gunderson),
3 which is faster on modern cpus and compresses a bit better. The old
4 hash function which uses only shifts is still available.
5 - allow user configurable hash table slots, which makes it possible
6 to use e.g. 16 bit offsets for a smaller hashtable (if your data is
7 always < 64kb).
8 - use _WIN32, not WIN32, when testing for windows (fails with bcc),
9 patch by Tamas Tevesz.

2 - fixed hash calculation in C♯ version (Tiago Freitas Leal). 12 - fixed hash calculation in C♯ version (Tiago Freitas Leal).
13 - unroll copy for small sizes, use memcpy for larger sizes,
14 greatly speeding up decompression in most cases.
15 - finally disable rep movsb - it's a big loss on modern intel cpus,
16 and only a small win on amd cpus.
17 - improve C++ compatibility of the code.
18 - slightly improve compressor speed.
19 - halved memory requirements for compressor on 64 bit architectures,
20 which can improve the speed quite a bit on older cpus.
