HELP - How to stop line break conversion?

[r . burton]

Hi,

We have a Linux CVS server and most clients are also running Linux. 
However, a laptop we have is running Windows and Cygwin for the GNU
tools, but when we checkout code from the CVS tree, cvs converts the
text files from unix-style line breaks to Windows-style line breaks,
which Bison does not like...  How can we stop WinCVS/cvs/whatever is
to blame from converting text files, so that the Windows machine has
Unix-style files on?

This is rather urgent, so a direct email reply would be gratefully
received.

Thanks,
