an overview on the state. The transfer via native git protocol does not work 
and cannot be made working without major surgery(*). Theoretically, using 
netcat (nc) as GIT_PROXY_COMMAND should work, but not in my setup for some 
reason that I still do not know.

(*) The reason is that on Windows read() and write() cannot operate on 
descriptors created by socket(). A work-around is to implement a (threaded) 
proxy, but that's almost the same as if netcat were used as 
GIT_PROXY_COMMAND.

Actually, I believe it can for the NT series kernels (at least 2000 or 
later, not sure about the earlier ones), but not for the DOS-based ones.

The trick is to use _open_osfhandle() to convert the file handle (a 
WinAPI construct) to a file descriptor (which in Windows is a construct 
of the C library.)

In 9x/ME, a socket isn't represented by a file handle, so 
_open_osfhandle() doesn't work on a socket object.
