Ok, so you get the same results as me.  They are both wrong.  The script 
should only print the first line.

I just tried something, I made a file like this: "0000000   a   b   c 
\r  \r  \n   d   e   f  \r  \r  \n".  Then the perl script shows only 
the first line.

In 5.6: setting 'binmode LOG, ":crlf";' would set the line-separator to 
"\r\n".
In 5.8: setting 'binmode LOG, ":crlf";' sets the line-separator to "\r" 
+ $/.  So, given that I've already set the line-separator to "\r\n" it 
ends up as "\r\r\n" for that file.

Does anybody have access to a U/Linux machine with perl 5.8 on it?  Can 
they run that test script on it?  I'd like to know if this is only a 
problem with cygwin-perl or with perl in general.
