This is really ugly because, on one hand cin is seen with the right
type and on the other hand as array[] at the code level -- I wouldn't
to debug such a mess.

Can a conforming program detect the followiing declaration for cin:

	extern istream& cin;	// can a conforming program detect?

so that we can do

	char __cin_storage[sizeof(istream)]
	     __attribute__ ((__align (__alignof__ (istream))));

	istream& cin = *(istream*)(&__cin_storage[0]);

Or is that still sufering from the init issue?
