Matthias,

Get a copy of Greg's messages and try procesing them with 0.10.3.  It 
doesn't work properly.  Given the long sequences of x's in 3.txt and 4.txt, 
the flex code keeps asking for more data to fill its buffer.  Eventually it 
asks for 1 byte and gets 0 bytes (using 0.10.3).  Flex interprets a return 
count of 0 as EOF and thinks it's done.
