Fwd: Re: CygWin adding CRs, hurting CVS client/server communications?

Tue Jul 1 00:58:00 GMT 2003

Well, I take that back...someone pointed me to 
http://www.gigascale.org/softdevel/faq/23.html, which contains instructions 
for reinstalling CygWin with text mode set to DOS, which actually fixes the 
problem (the remount procedure didn't work, as is warned in the 
article).  All I did was run the setup utility, selected DOS text mode, and 
selected the base/cygwin and devel/cvs packages for reinstallation...works 
like a charm now.  The contents of this article might be good fodder for 
the FAQs.  Cheers!
