version 0.3
  - added new gcc option for faster win32 binary
  - added link to used gcc 4.1.2 to gcc_make.bat as comment
  - very small changes
  - added dectection of iso without file extension
  - line end in source is now 78 (only for one printf its longer ;)

version 0.2
  - bugfix, buf was not initialized correctly
    we can decompress enwik8 correctly now :)
    thanks matt mahoney for reporting
    thanks nania for trying, but did u test your patch with enwik8?!

version 0.1
  - win32 version compiled with sse support (implemented what hook9 seems to
      do)
    your cpu will need sse (pentium3+, athlon-xp+)
    ATTENTION: sse math yields to slightly different results,
    output file can be some bytes smaller or bigger
    besides, no real problem.
    problem is only, two compiled versions of hook not doing exaclty the same
      math cant decompress files of each other
  - display KB/s (implemented what hook9 seems to do)
  - ported from c++ to c
  - fixed all -Wall warnings
  - indent -kr -i2
  - cosmetic changes
  - initialize buf with malloc() instead of bss
    (side effect: program can be packed with upx,
    already working packers will pack faster and more efficient,
    for example dwings great upack)
  - replaced Pokeb() with inline c
  - replaced Peekb() with inline c
  - replaced all goto instructions
  - enhanced performance for progress bar
  - added filter for IFF (TTF), use BMP instead of DEFAULT
  - renamed modified Hook v0.8e to freehook v0.1
