Hi,

Following patch addresses PR 4545 on mainline.

"I was mistaken in one piece that I submitted in PR libstdc++/4536.

 Rather, according to $27.6.2.5.3(6) the operator
 basic_ostream::operator<<(streambuf*) should tset badbit, not 
 failbit, if __sbin or __xtrct is set to 0."

	* include/bits/ostream.tcc (basic_ostream::op<<(streambuf*)): If
	__sbin or __xtrct are 0, set badbit, not failbit, per
	$27.6.2.5.3(6).
