The only problem is cvs has special code to do EOL munging itself.  I've 
tried to eliminate that cruft (or #ifdef it out) for the cygwin build, 
but I never tried to "certify" the pserver for use.  As far as I'm 
concerned, using the cygwin cvs as a pserver *server* is unsupported, 
although there have been rumors that it works.  For some people.  Under 
some (as usual, unspecified) conditions.

Of course, using cygwin cvs as a pserver *client* is always supported.

My point: to track down this issue will probably require getting dirty 
(e.g. tracing thru the code).
