 164 -------------------------
 165 - The bug was fixed in LzmaDecode.c (ANSI-C LZMA Decoder):

 197   and decompressing speed and shows rating values.
 198   Also it checks hardware errors.

 202 -------------------------
 203 - C++ LZMA Encoder/Decoder code now is more portable

 210     LzmaDecode.c / RangeDecoderReadByte
 211     .....
 212     {
 213       rd->ExtraBytes = 1;
 214       return 0xFF;
