They might not be using the same CVS programs, though. It appears that 
Windows CVS (which, for example, red_bat uses) translates line endings 
to CRLF, which is why it passed the regression tests, but MinGW CVS does 
not, which I think is is why narwahl and vaquita failed and why dawn_bat 
will probably fail next go round. brown_bat is on Cygwin and we should 
not expect a change there.
