    initial v1  
    11Reasons could be:
    2 1.) a lot of changes were done between 2 checkins
    3 2.) "C" source files did not contain newlines at the end
    4 3.) all ASCII files contain svn:eol-style property, I had to remove it for some files because svn was complaining about inconsisent line end or so
