  Modified:    examples encoder_example.c
               win32/experimental/encoderwin ReadMe.txt encoderwin.dsp
  Added:       win32/experimental/wincompat README.txt getopt.c getopt.h
                        getopt_long.c unistd.h
  Removed:     win32/experimental/encoderwin encoderwin.c
  Log:
  experimental win32 encoder now uses the common encoder_sample.c file in theora/examples. Should eliminate any differences when looking for bitstream differences between platforms
