My Jenkins slave running on Windows XP is checking out my files from CVS with a Windows format.

I am building inside cygwin, so my build is failing with this message:
error C4335: Mac file format detected: please convert the source file to either DOS or UNIX format

One specific file looks like this when I run 'file' on it. In Jenkins workspace it looks like this:

L_LicenceObjectBasePtr.cpp: ASCII C++ program text, with CRLF, CR line terminators
The file in vi shows "^M$" at the line ending (\r\n)

If I checkout the source using cygwin, the output of 'file' on the same file looks like this:

L_LicenceObjectBasePtr.cpp: ASCII C++ program text, with CRLF line terminators
The file in vi shows "$" at the line ending. (\n)

I am attempting to run dos2unix on my files before building, but this is not the most ideal solution.

Is there another know solution to this, but why would the line endings of my files coming out of CVS be different for via Jenkins than via cygwin.
