std_fstream.h (_M_destroy_pback): Use _M_in_beg instead of unnecessarily taking the address of _M_pback.
2003-06-02 Paolo Carlini <pcarlini@unitus.it>
* include/std/std_fstream.h (_M_destroy_pback): Use _M_in_beg
instead of unnecessarily taking the address of _M_pback.
(xsgetn): Simplify slightly for a single char pback buffer.
2003-06-02 Paolo Carlini <pcarlini@unitus.it>
* include/bits/sstream.tcc (seekoff): Remove four unnecessary
variables and two 'if', clean up.
2003-06-02 Paolo Carlini <pcarlini@unitus.it>
* include/bits/sstream.tcc (seekpos): Test against _M_out_lim
not _M_out_end, since the former actually points to the string
end (vs buffer end).
* testsuite/27_io/basic_stringbuf/seekpos/char/3.cc: New.
