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