Right, SVN internally always stores text files with only \n as
lineending, however....

You can have a different lineending on the working copy really easily by
using svn:eol-style property (on each file where you want it). That way
you could checkout on win32 and automatically get win32-lineendings for
those files that should have them. Then you can build/install/package
that without problems. (only drawback here is that you can't use such a
win32 working copy from unix, via nfs or such and you need to take extra
care when copying diffs around)

Alternatively you could let your program be intelligent enough to guess
the lineending by checking wether its \r\n or just \n and adjust the
reading of the conf files apropriately.

I'm not sure its the buildsystems job to fix lineendings for you.
