Mainly because I already had cygwin installed on my new machine and I
did not want to have to search for a free windows svn client. I did
not know using the cygwin version could cause problems.

When you mention line ending problems, I had just run into a line
ending problem but it was not caused by that. I caused this one.. The
svn server is on linux and I imported a few old projects from cvs to
svn and it appears that changed line endings from windows to unix. I
did not know till I tried to open a visual C 6 project and nothing
happened.
