When I have file that was converted from dos to unix format (or from
unix to dos) git genereta big diff. But anyway, c++ compiler works well
with both formats and in this case I simply convert file to dos format
and git shows again nice diff. If unix format was commited to git I
simply change the format and commit that file again.

That's awful!

If you are tring to build history that looks good - you are right this is
a terrible workflow.

The only trouble is the rebase, it does not like \r\n ending and othen
produce unexpected merge conflict. But I don't use rebse to othen to
realy investigate and try to solve the problem.

Well, if everybody thinks like you, maybe we do not have to change
anything for Windows after all?

I still wish to have working rebase so if git will hanle somehow \r\n it
would be nice. But please do not produce the same behavior as cvs does:
under cygwin it still use \n !

Cygwin != Windows, Cygwin is a POSIX emulation layer with the explicit goal
of providing user tools behaving exactly as they do under Linux, and this
includes line ending style.

So, the Cygwin ports of various Linux tools are not expected to satisfy
users who want native Win32 behavior. This is where the mingw port of git
fits in. Yes, under Cygwin git can track files with \r\n endings, but: 
1) Those projects are not portable to non-windows platforms, and 
2) As you noted, git will have trouble with rebase, merge, etc. as there is
an assumption of \n endings throughout.

A proper win32 port will accept any of \n, \r\n as valid line endings (add
\r to support Mac pre-OSX if anyone cares, I still occasionally see such
files), treat any of them as semantically equal, and enforce the user's
chosen style (\n or \r\n) on output. cvsnt and svn under Windows do this
today, serving up "text" files from the same repository with \n endings or
\r\n endings depending upon the client, and is what we need a win32 git to
do as well.
