[RFD]: fcntl call substituting `setmode'

[Corinna Vinschen]

Hi all,

I'm just using the `setmode' function and I wonder
if it wouldn't be a nice thing to have some sort of
fcntl call for that, eg.

	fcntl(fd, F_SETMODE, O_TEXT);

and a corresponding:

	int mode;
	fcntl(fd, F_GETMODE, &mode);

and -- because it's that nice -- a substitute for
`get_osfhandle()':

	HANDLE hdl;
	fcntl(fd, F_GETOSFHDL, &hdl);

I would like that more than the Windowish calls
and we could get rid of the io.h file for cygwin.
Not instantly of course.
