streambuf.tcc (__copy_streambufs): Don't use in_avail(), simplify.

Browse Source 
2003-04-26  Paolo Carlini  <pcarlini@unitus.it>

	* include/bits/streambuf.tcc (__copy_streambufs): Don't
	use in_avail(), simplify.

2003-04-26  Paolo Carlini  <pcarlini@unitus.it>

	* include/std/std_sstream.h (setbuf): don't set _M_buf_size,
	in basic_stringbuf it's unused.

	* include/std/std_sstream.h (underflow): consistently use
	_M_in_cur, not gptr().
